#8803: ghc panic ((!!): index too large) when building some packages ----------------------------------+--------------------------------------- Reporter: joelteon | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.8.1-rc1 Keywords: | Operating System: MacOS X Architecture: x86_64 (amd64) | Type of failure: Compile-time crash Difficulty: Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | ----------------------------------+--------------------------------------- I'm not 100% sure what the cause of this is, because I can't get a reproducible test case. If I try to build `postgresql-simple`, this is the output from cabal (with `-v3`): https://gist.github.com/anonymous/bda9095cee1eda5640c0 Wondered whether it was related to hs-boot files, but I cannot reproduce the error with the basic example from http://www.haskell.org/ghc/docs/7.0.3/html/users_guide/separate- compilation.html. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8803 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
