#14135: PatternSynonyms regression in GHC HEAD (expectJust mkOneConFull) -------------------------------------+------------------------------------- Reporter: RyanGlScott | Owner: dfeuer Type: bug | Status: new Priority: highest | Milestone: 8.4.1 Component: Compiler | Version: 8.3 Resolution: | Keywords: | PatternSynonyms Operating System: Unknown/Multiple | Architecture: Type of failure: Compile-time | Unknown/Multiple crash or panic | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Phab:D3981 Wiki Page: | -------------------------------------+------------------------------------- Comment (by dfeuer): Something really weird is going on. I tried building GHC with profiling to trace down the problem, but that made it go away. If GHC is encountering a correctness problems ''compiling itself'', then we have serious trouble on our hands. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14135#comment:16 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
