Issues list

Trait resolution fails, and then rustc hangs. A-associated-items Area: Associated items (types, constants & functions) A-higher-ranked Area: Higher-ranked things (e.g., lifetimes, types, trait bounds aka HRTBs) A-trait-system Area: Trait system C-bug Category: This is a bug. fixed-by-next-solver Fixed by the next-generation trait solver, `-Znext-solver`. I-hang Issue: The compiler never terminates, due to infinite loops, deadlock, livelock, etc. T-compiler Relevant to the compiler team, which will review and decide on the PR/issue. T-types Relevant to the types team, which will review and decide on the PR/issue.
