#8586: internal error: evacuate(static): strange closure type 5189 ----------------------------+------------------------------- Reporter: guest | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.6.3 Keywords: crash | Operating System: Windows Architecture: x86 | Type of failure: GHCi crash Difficulty: Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | ----------------------------+------------------------------- I cannot reproduce this reliably, but it happened once. Here’s what I did: * Install Yesod * Scaffold a blank Yesod project with no DB * Run GHCi * :l Foundation.hs * :info AForm Output: {{{ newtype AForm m a = AForm {unAForm :: (HandlerSite m, [Text]) -> Maybe (Env, FileEnv) -> Ints -> m (FormResult a, [FieldView (HandlerSite m)] -> [FieldView (HandlerSite m)], Ints, Enctype)} -- Defined in `Yesod.Form.Types' instance Monad m => Functor (AForm m) -- Defined in `Yesod.Form.Types' instance (Monad m, Monoid a) => Monoid (AForm m a) -- Defined in `Yesod.Form.Types' instance MonadTransghc.exe: internal error: evacuate(static): strange closure type 5189 (GHC version 7.6.3 for i386_unknown_mingw32) Please report this as a GHC bug: http://www.haskell.org/ghc/reportabug This application has requested the Runtime to terminate it in an unusual way. Please contact the application's support team for more information. }}} (P.S. I chose 'x86' for the Architecture because it’s running as 32-bit, but I’m actually using 64-bit Windows.) -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8586 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
