#10335: Failure to construct superclasses in instance -------------------------------------+------------------------------------- Reporter: simonpj | Owner: Type: bug | Status: merge Priority: normal | Milestone: Component: Compiler | Version: 7.10.1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: None/Unknown | Unknown/Multiple Blocked By: | Test Case: Related Tickets: | typecheck/should_compile/T10335 | Blocking: | Differential Revisions: -------------------------------------+------------------------------------- Changes (by simonpj): * status: new => merge * testcase: => typecheck/should_compile/T10335 Comment: Fixed, although the patch probably won't apply very nicely to 7.10.2, because it meddles with `TcEvidence` which has changed since 7.10. But this patch effectively reverts one of the changes to `TcEvidence` so while it won't apply automatically, it won't be hard either. I'm inclined to think it's worth merging. I can help.
