The problem

It append on few of my user since, I have this crash on crashlytics.

Crashlytics indicate :
The stack trace indicates that heap corruption may have caused your app to crash. Memory corruption can occur pretty easily from freeing a dangling pointer, a thread race, or bad pointer arithmetic. The important thing to keep in mind is that the resulting crash may happen long after the initial corruption. As a result, the stack trace for this crash might not provide any clues to the location of the bug in your code. However, you can still fix memory issues with tools from Apple. For speedy resolution of memory corruption issues, we recommend regularly auditing your app with Xcode’s memory debugging facilities: Visual Memory Debugger, Zombies Instrument, Address Sanitizer, Thread Sanitizer and malloc diagnostics.

Relevant Code:

I'm using a subclasse of NSOperation to execute this code:

- (void)main {
    @try {
      
        // Add test for min version
        self.remoteConfig = [FIRRemoteConfig remoteConfig];
        FIRRemoteConfigSettings *remoteConfigSettings = [[FIRRemoteConfigSettings alloc] initWithDeveloperModeEnabled:NO];
        self.remoteConfig.configSettings = remoteConfigSettings;
        
        [self.remoteConfig fetchWithExpirationDuration:5 completionHandler:^(FIRRemoteConfigFetchStatus status, NSError *error) {
            if (status == FIRRemoteConfigFetchStatusSuccess) {
                [self.remoteConfig activateFetched];
            }
            [self completeOperation];
        }];
        
    }
    @catch(...) {
        // Do not rethrow exceptions.
    }
}

I'm also using FirebaseAnalytics but I can't found in the logs witch part of my code generate this crash. Which seems to be internal.

Can you give more details how you set up the NSOperation to execute the RemoteConfig code? Is it a background operation? Are you running it on main queue?

It seems like that conflicts with what's inside InstanceID, which also uses NSOperation. But if you can provide more details that will help us to repo the case. Thank you!

Thanks for your reactivity,
The quality of service of the background operation is set to NSQualityOfServiceBackground
I don't run this on main queue, because I execute multiple operation in background.
Is it the problem ?

Here is the full class:

@interface OFMinumumVersionCheckOperation : NSOperation {
    BOOL executing;
    BOOL finished;
}

@property (nonatomic, strong) FIRRemoteConfig* remoteConfig;

@end

#import "OFMinumumVersionCheckOperation.h"

@implementation OFMinumumVersionCheckOperation

- (id)init {
    self = [super init];
    if (self) {
        executing = NO;
        finished = NO;
    }
    return self;
}

- (BOOL)isConcurrent {
    return YES;
}

- (BOOL)isExecuting {
    return executing;
}

- (BOOL)isFinished {
    return finished;
}

- (void)start {
    // Always check for cancellation before launching the task.
    if ([self isCancelled])
    {
        // Must move the operation to the finished state if it is canceled.
        [self willChangeValueForKey:@"isFinished"];
        finished = YES;
        [self didChangeValueForKey:@"isFinished"];
        return;
    }
    
    // If the operation is not canceled, begin executing the task.
    [self willChangeValueForKey:@"isExecuting"];
    [NSThread detachNewThreadSelector:@selector(main) toTarget:self withObject:nil];
    executing = YES;
    [self didChangeValueForKey:@"isExecuting"];
}


- (void)main {
    @try {
      
        // Add test for min version
        self.remoteConfig = [FIRRemoteConfig remoteConfig];
        FIRRemoteConfigSettings *remoteConfigSettings = [[FIRRemoteConfigSettings alloc] initWithDeveloperModeEnabled:NO];
        self.remoteConfig.configSettings = remoteConfigSettings;
      
        [self.remoteConfig fetchWithExpirationDuration:5 completionHandler:^(FIRRemoteConfigFetchStatus status, NSError *error) {
            if (status == FIRRemoteConfigFetchStatusSuccess) {
                [self.remoteConfig activateFetched];
            }
            [self completeOperation];
        }];
        
    }
    @catch(...) {
        // Do not rethrow exceptions.
    }
}

- (void)completeOperation {
    [self willChangeValueForKey:@"isFinished"];
    [self willChangeValueForKey:@"isExecuting"];
    
    executing = NO;
    finished = YES;
    
    [self didChangeValueForKey:@"isExecuting"];
    [self didChangeValueForKey:@"isFinished"];
}


@end

I have a manager with configure the nsoperationqueue like this:

self.migrationQueue = [[NSOperationQueue alloc] init];
        if ([self.migrationQueue respondsToSelector:@selector(setQualityOfService:)]) {
             self.migrationQueue.qualityOfService = NSQualityOfServiceBackground;
        }
        self.migrationQueue.maxConcurrentOperationCount = 1;

I had the operation this way:

 OFMinumumVersionCheckOperation* operation = [[OFMinumumVersionCheckOperation alloc] init];
               [self.migrationQueue addOperation:operation];

Edit:
Sorry I can not post a stacktrace, but I am not writing to the RemoteConfig from a background thread. The call to FIRLoggerWrapper logWithLevel:withService:withCode:withMessage:withArgs: thats crashing is called from a background thread tho.

I have the same issue, but I am using Firebase only from main queue.

If you're having the same issue, please post stack traces as well--the nature of this crash means we won't necessarily be able to diagnose it from a single stack trace. If you're able to reproduce it locally, please try running your project with Xcode's built-in diagnostic tools enabled (NSZombies, asan, tsan), and post any traces here as well.

Also note it's not safe to write to the FIRRemoteConfig shared instance from a background thread, as the FIRRemoteConfig class is not thread-safe.

I can change the main of the operation like this :
But i'm not sure that the completion operation will be on the good thread can't find a way to be back on the thread of the operation... Any advise ?

- (void)main {
    @try {
        dispatch_async(dispatch_get_main_queue(), ^{
            // Add test for min version
            self.remoteConfig = [FIRRemoteConfig remoteConfig];
            FIRRemoteConfigSettings *remoteConfigSettings = [[FIRRemoteConfigSettings alloc] initWithDeveloperModeEnabled:NO];
            self.remoteConfig.configSettings = remoteConfigSettings;
           
            [self.remoteConfig fetchWithExpirationDuration:5 completionHandler:^(FIRRemoteConfigFetchStatus status, NSError *error) {
                if (status == FIRRemoteConfigFetchStatusSuccess) {
                    [self.remoteConfig activateFetched];
                }
                [self completeOperation];
            }];
        });
        
    }
    @catch(...) {
        // Do not rethrow exceptions.

}

@mgstudio the completion handler is always executed on the main queue, even if you call one of the fetch methods from a background queue.

@morganchen12 does this solution to use GCD seems the correct solution for you ?

@mgstudio Can you provide the full stack trace logs? I'm trying to figure out whether it's exactly the same as @ogres.

Thanks @chliangGoogle, as my app is crashing due to Firebase too, I was wondering when are you planning to make a release with this fix in it? I would like to plan a release of my app with updated Firebase SDK.

The fix is planned for the next release, but we don't pre-announce dates. We'll update this issue when the fix is available.

@robinkunde

4.6.0 was just released (https://firebase.google.com/support/release-notes/ios). Looks like it contains the fix.

With the upcoming #444 PR and CocoaPods 1.4.0, we can eliminate the calls via reflection in InstanceID to FirebaseCore. It's not clear why the reflection based calls would cause this crash, but making the change could either eliminate the crash or provide more clarity about it.

This case is still occurred with 4.6.0!!

Are you doing something about this in progress or not?

In my opinion, exchanging the deprecated FIRInstanceID to the Messaging might be related with this case..
How about this?

@paulb777 now that we deprecated FirebaseCommunity, should we revert the reflection code?

@chliangGoogle Yes, reflection code is no longer needed for FirebaseInstanceID to make calls into FirebaseCore.

We are removing the reflection calls that causing the crash. Should be out for the next release.

Just so that you are aware of the severity: this bug is the Nr.1 reason for all the crashes in our App. It's high above any other source of crashes.

I'm seeing the same here. #1 crash in our app. When I see it in our app, there is always one or two threads waiting or executing sqlite ( ours or firebases ). Could be somehow related.

Likewise, this has taken over the number one spot in Crashlytics for our app.

This seems to be a "me too" day so if it helps, I can also confirm this crash happens frequently (unfortunately not frequently enough to be reproducible on my side) and has been the number one crash in my 4 apps.

This should be fixed in the 4.8.0 release of Firebase, feel free to reopen if that's not the case.

Thanks for the fix, I do not experience this bug anymore in 4.8.0. But I got some other:

http://crashes.to/s/a8fa82e0118
http://crashes.to/s/b4162fade4d
http://crashes.to/s/48bb2b13d6f

But this are happening very rare, nothing severe like the FIRLoggerWrapper issue.

@Jeheonjeol The fix is actually in FirebaseInstanceID 2.0.8 which is the default for Firebase 4.8.0. It looks like you may be overriding the InstanceID pod version, since your Podfile.lock shows FirebaseInstanceID 2.0.6.

@DarkoDamjanovic Thanks for the feedback. One of the other crashes you're seeing is being tracked in #431.

I'm going to lock this issue for comments. If you see additional crashes, please open a new issue with the backtrace.
