#13233: typePrimRep panic while compiling GHC with profiling -------------------------------------+------------------------------------- Reporter: bgamari | Owner: Type: bug | Status: new Priority: highest | Milestone: 8.2.1 Component: Compiler | Version: 8.0.1 Resolution: | Keywords: 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): Wiki Page: | -------------------------------------+------------------------------------- Comment (by bgamari): Interesting, the tidy core shows, {{{#!hs -- RHS size: {terms: 1, types: 4, coercions: 0} StgCmmMonad.$fHasDynFlagsFCode2 :: CgInfoDownwards -> CgState -> (# CgInfoDownwards, CgState #) [GblId, Unf=Unf{Src=<vanilla>, TopLvl=True, Value=False, ConLike=False, WorkFree=False, Expandable=False, Guidance=IF_ARGS [] 0 10}] StgCmmMonad.$fHasDynFlagsFCode2 = ghc-prim-0.5.0.0:GHC.Prim.(#,#) @ 'ghc-prim-0.5.0.0:GHC.Types.LiftedRep @ 'ghc-prim-0.5.0.0:GHC.Types.LiftedRep @ CgInfoDownwards @ CgState }}} Which we would have been able to eta expand without any trouble. It must be something in CorePrep that is gumming up the works. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13233#comment:12 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
