#12055: Typechecker panic instead of proper error -------------------------------------+------------------------------------- Reporter: bgamari | Owner: Type: bug | Status: new Priority: normal | Milestone: 8.0.2 Component: Compiler (Type | Version: 8.0.1 checker) | Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: Compile-time | Test Case: crash | polykinds/T12055, T12055a Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Changes (by simonpj): * testcase: => polykinds/T12055, T12055a Comment: I've added two regressions test. HEAD is fine, but there really is a bug in GHC 8.0, producing "GHC internal error" when `FlexibleContexts` is omitted. It doesn't look that high a priority to me. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/12055#comment:5 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
