Don't install default projection bound for return-position `impl Trait` in trait methods with no body This ensures that we never try to project to an opaque type in a trait method that has no body to infer its hidden type, which means we never later call `type_of` on that opaque. This is because opaque types try to reveal their hidden type when proving auto traits. I thought about this a lot, and I think this is a fix that's less likely to introduce other strange downstream ICEs than #113461. Fixes #113434 r? `@spastorino` |
