#10527: Panic Simplifier ticks exhausted with type families -------------------------------------+------------------------------------- Reporter: sopvop | Owner: bgamari Type: bug | Status: new Priority: highest | Milestone: 7.10.2 Component: Compiler | Version: 7.10.1-rc1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: None/Unknown | Unknown/Multiple Blocked By: | Test Case: Related Tickets: | Blocking: | Differential Revisions: -------------------------------------+------------------------------------- Comment (by bgamari): Simon has identified that the issue is the simplifier expending a great deal of effort simplifying an argument which is ultimately ignored by the callee. I have merged 07a1f32e8bacecd450112607df3fdf39e553c91e into the `ghc-7.10` branch which should resolve this for 7.10.2. Simonpj is working on a more thorough fix for `master`. I'll leave this open until the latter fix has been merged. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10527#comment:21 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
