bors 0ef2b4a29b Auto merge of #85755 - b-naber:unexpected_concrete_region, r=nikomatsakis ... Replace parent substs of associated types with inference vars in borrow checker Fixes https://github.com/rust-lang/rust/issues/83190 Fixes https://github.com/rust-lang/rust/issues/78450 When we normalize an associated type that refers to an opaque type, it can happen that the substs of the associated type do not occur in the projection (they are parent substs). We previously didn't replace those substs with inference vars, which left a concrete region after all regions should have already been replaced with inference vars and triggered a `delay_span_bug`. After we normalize the opaque type, we now try to replace any remaining concrete regions with inference vars.		2021-06-17 12:31:56 +00:00
