![]() Emit error in `collecting_trait_impl_trait_tys` on mismatched signatures Previously, a `delay_span_bug` was isssued, failing normalization. This create a `TyKind::Error` in the signature, which caused `compare_predicate_entailment` to swallow its signature mismatch error, causing ICEs because no error was emitted. fixes #104183 r? ``@compiler-errors`` |
