ICE: trimmed_def_paths constructed, assertion failed: !new_self_ty.has_escaping_bound_vars()

[Manishearth]

Code

Unfortunately I'm unable to reduce the testcase, but you can run it by opening https://github.com/Manishearth/icu4x/tree/ice-trimmed-def-paths. and from the components/properties directory, running cargo test --doc ascii_hex_digit. This code is in the midst of a refactor so most of the other tests will not pass.

I suspect it has to do with the complicated trait stuff going on in provider.rs interacting with the docs.rs/yoke crate (cc @jackh726 @eddyb) but I'm not sure.

Meta

Bug occurs on 1.60 stable and current nightly.

[jackh726]

Any way you could run this with a compiler with debug info included? Line numbers would be helpful for the stacktrace. It looks like there's a bug in the error reporting path.

[Manishearth]

@jackh726 as in, build one locally? yeah can do

[jackh726]

Yes :)

[jackh726]

Actually, probably not needed. This code is wonky:

rust/compiler/rustc_trait_selection/src/traits/error_reporting/suggestions.rs

Line 884 in 4ca19e0

let orig_ty = old_pred.self_ty().skip_binder();

[jackh726]

Probably the best way to fix this would be to make mk_trait_obligation_with_new_self_ty take a Binder<(TraitRef, Ty)>.

I might or might not be able to find the time to work on this, but it's pretty easy and I can mentor someone. There's also quite a bit of code that calls mk_trait_obligation_with_new_self_ty that I think can be cleaned up re. binder handling.

I think the more time-intensive part of this bug is getting a test case 😉
