[Nashenas88]

Summary

thread 'rustc' panicked at /b/s/w/ir/x/w/fuchsia-third_party-rust/compiler/rustc_middle/src/ty/mod.rs:1239:9:
`<(std::vec::Vec<&str>, std::option::Option<&diagnostics_hierarchy::Property>) as std::marker::Copy>` has escaping bound vars, so it cannot be wrapped in a dummy binder.

Not yet minimized. Seems to come from https://cs.opensource.google/fuchsia/fuchsia/+/main:src/connectivity/network/tests/integration/inspect/src/lib.rs;l=1617;drc=40f5937c45609e364e4914cc5b35db2b2b951717

Where diagnostics_hierarchy::Property is defined as seen here https://fuchsia-docs.firebaseapp.com/rust/diagnostics_hierarchy/enum.Property.html

[Nashenas88]

I'm currently working to produce a minimized repro.

[Centri3]

Looks like it's from the filter_map_bool_then (one of my own, sorry! 😅)

The issue seems to be in this line:

rust-clippy/clippy_lints/src/methods/filter_map_bool_then.rs

Line 24 in 7c595b4

&& is_copy(cx, cx.typeck_results().node_type(param_ty.hir_id).peel_refs())

, though I have no idea why that's an issue.

Once that minimized repro is available I'll take a look into this.

[Nashenas88]

Got the minimized repro:

fn check<'a>(iter: impl Iterator<Item = (&'a str, &'a str)>) -> Vec<&'a str> {
    iter.filter_map(|(_, s): (&str, _)| Some(s)).collect()
}

[compiler-errors]

@Centri3:

node_type(param_ty.hir_id) likely has bound vars from the closure's own binder.

to fix, you can probably take that type, wrap it in a binder with ty::Binder::bind_with_vars using the TyCtxt::late_bound_vars of the closure's hir id, and then liberate the binder to conver them into free regions.

That would be the least hacky way to deal with those bound vars.

[Nashenas88]

If this is a new lint, could we revert the lint to prevent the ICE from triggering while the fix is being worked on? We don't know exactly which commit this started in since our toolchain was also broken by rust-lang/rust#114597 earlier.

[Centri3]

It was this one. #11115
You could revert it locally and build it yourself, setting up a custom toolchain for exactly that clippy version, but not practically. We'd need to wait until the next sync (which is today, I think!) but getting it into master without approving my own PR would likely take longer.

I doubt there's any reason we can't make a PR against rustc itself, but I don't think I've seen that done before for a clippy issue. Maybe we could do that instead, though that'd result in the two being out of sync intentionally.

[tmandry]

I believe a PR on the rust repo would follow the revert policy at https://forge.rust-lang.org/compiler/reviews.html#reverts, but since it's a T-compiler policy it doesn't automatically apply here. The policy says it's okay to self-approve reverts.

edit: The other reason it's nicer to revert on the rust repo is that we don't have to wait for the next subtree sync.

[Centri3]

I think I'll revert it manually and open a PR for that. However, this will result in some issues come the next sync so heads up @flip1995, come the next sync you'll likely need to ignore that PR on the rust -> clippy side, but revert it on clippy -> rust.

[blyxyas]

Before completely reverting the lint, did you try @compiler-errors' solution? In the PR it says that the ICE is unpreventable, but maybe it would fix it.

[Centri3]

Yes, I opened a PR for that (#11318). I mean unpreventable in that it cannot be prevented by the user because in some cases, type annotations are needed (which creates late bound vars, for some reason)
