#8834: 64-bit windows cabal.exe segfaults in GC ---------------------------------+---------------------------------- Reporter: awson | Owner: Type: bug | Status: new Priority: highest | Milestone: 7.8.1 Component: None | Version: 7.8.1-rc2 Resolution: | Keywords: Operating System: Windows | Architecture: x86_64 (amd64) Type of failure: None/Unknown | Difficulty: Unknown Test Case: | Blocked By: Blocking: | Related Tickets: ---------------------------------+---------------------------------- Comment (by awson): 1. I've reduced this case to the following: {{{ import qualified Data.ByteString.Char8 as BSS main :: IO () main = do cache <- BSS.readFile "00-index.cache" print (length $ BSS.lines cache) }}} `00-index.cache` is hackage packages cache file. Even truncated to 12000 lines it gives segfault. 2. After bisecting I've found the [https://github.com/ghc/ghc/commit/ad15c2b4bd37082ce989268b3d2f86a2cd34386a problematic commit]. I don't understand what is going here. I think I've made absolutely my best in this situation. Please, someone fix this! I feel myself completely alone fighting with numerous win64 bugs which nobody ever bother to look into. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8834#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
