#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): Results so far: 1. If I compile GHC+D3981 with either `quick` or `prof`, then T13822 works fine, and passes Core lint. 2. If I compile GHC+D3981 with devel2, then it crashes as described in the differential comments. I'm hoping this info can help someone point me to a likely area to look for the problem. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14135#comment:17 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
