There was a problem hiding this comment.
Why do we not have a downgrade method for RefMut -> Ref? cc @rust-lang/libs

cstore: return an immutable borrow from `visible_parent_map` This prevents an ICE when `visible_parent_map` is called multiple times, for example when an item referenced in an impl signature is imported from an `extern crate` statement occurs within an impl. Fixes rust-lang#41053. r? @eddyb
