#8381: Simplifier ticks exhausted ----------------------------------+--------------------------------------- Reporter: guest | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.6.3 Keywords: | Operating System: MacOS X Architecture: x86_64 (amd64) | Type of failure: Compile-time crash Difficulty: Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | ----------------------------------+--------------------------------------- Trying to build a (rather simple) project using '''cabal''' I get the following error message on a valid program: ghc: panic! (the 'impossible' happened) (GHC version 7.6.3 for i386-apple-darwin): Simplifier ticks exhausted When trying UnfoldingDone a_syQ{v} [lid] To increase the limit, use -fsimpl-tick-factor=N (default 100) If you need to do this, let GHC HQ know, and what factor you needed To see detailed counts use -ddump-simpl-stats Total ticks: 5080 I tried to increase the limit without success. More oddly if I try to build directly the program using '''ghc''' (same version) it succeeds, therefore I suspect that cabal is somehow the source of my problem. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8381 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
