'rustc --pretty typed' fails for hello world

[richard-uk1]

(edited to update syntax)

Command is

rustc --pretty typed hello.rs

Code is (hello.rs)

/*
 *
 */
fn main() {
    println!("Hello, world");
}

[richard-uk1]

If you want me to do some work to get more debugging info I'm willing to do this.

[passy]

I get the same thing with rustc 0.5.

[catamorphism]

I wouldn't be surprised if ---pretty typed has bitrotted -- no further debugging necessary at this point. Thanks for reporting it!

[graydon]

reproduced on 2013-03-22

[graydon]

non-critical for 0.6, de-milestoning

[catamorphism]

Reproduced with 0252c30 -- nominating for milestone 5, production-ready

[graydon]

just a bug, removing milestone/nomination.

[emberian]

This still fails, but not with an ICE. It just... doesn't print anything.

[thestinger]

Still fails with fn main() { println!("Hello world") }

[chris-morgan]

@thestinger that's because of #7754 (new formatting uses fixed-size vectors, which is where the problem really is).

[lilyball]

As documented in #7754, the problem here is a written type that includes an integral expression. Trivial reproduction case:

fn main() {
    let _: [(), ..1u] = [()];
}

As @chris-morgan mentioned earlier, this is causing a problem with println!() (and anything else that uses format!() machinery internally) because the macro expansion includes a fixed-size vector type.

[huonw]

Fixed by #15804, landed in #16092.
