There was a problem hiding this comment.
Github didn't recognize the file being moved, but I gave it a better name. Also, there's no reason for us to be using #[test] here -- it's not necessary to reproduce the ICE; all that is necessary is a foreign crate.

Rollup merge of rust-lang#124875 - compiler-errors:more-diagnostics-ices, r=estebank Fix more ICEs in `diagnostic::on_unimplemented` There were 8 other calls to `expect_local` left in `on_unimplemented.rs` -- all of which (afaict) could be turned into ICEs. I would really like to see validation of `on_unimplemented` separated from parsing, so we only emit errors here: https://github.com/rust-lang/rust/blob/a60f077c38fe66d05449919842d3d73e3299bbab/compiler/rustc_hir_analysis/src/check/check.rs#L836-L839 ...And gracefully fail instead when emitting trait predicate failures, not *ever* even trying to emit an error or a lint. But that's left for a separate PR. r? `@estebank`

Beta backports approved as per compiler team on Zulip. A backport PR will be authored by the release team at the end of the current development cycle. Stable backport: same reasoning as for #124683: does not justify a dot release but this backport could jump on that train, if a dot release is planned for other reasons @rustbot label +beta-accepted +stable-accepted |
