#8743: The impossible happened : Prelude.(!!): index too large ---------------------------------------+---------------------------------- Reporter: erikd | Owner: Type: bug | Status: new Priority: highest | Milestone: 7.8.1 Component: Compiler | Version: 7.8.1-rc1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: x86_64 (amd64) Type of failure: Compile-time crash | Difficulty: Unknown Test Case: | Blocked By: Blocking: | Related Tickets: ---------------------------------------+---------------------------------- Comment (by rwbarton): I'm trying to massage GHC into giving me a proper stack trace (with `-xc`) but for now I can tell you the exception occurs somewhere inside `WorkWrap.splitFun`. (Which doesn't use `!!` directly, naturally...) -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8743#comment:3 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
