#9445: GHC Panic: Tick Exhausted with high factor -------------------------------------+------------------------------------- Reporter: adinapoli | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.8.3 Resolution: | Keywords: panic Operating System: MacOS X | Architecture: Unknown/Multiple Type of failure: | Difficulty: Unknown None/Unknown | Blocked By: Test Case: | Related Tickets: 5539 Blocking: | Differential Revisions: | -------------------------------------+------------------------------------- Comment (by Masei): The error seems to be caused by the Num instance. abs needs a tick-factor of 109 and signum a factor of 1630. Disabling rewrite-rules (-fno-enable-rewrite-rules) let it compile again. I peek at the ghc-source but don't found any related rules. Hope it helps anyway. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9445#comment:4 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
