#8834: 64-bit windows cabal.exe segfaults in GC ----------------------------------+---------------------------------- Reporter: awson | Owner: Type: bug | Status: patch Priority: highest | Milestone: 7.8.1 Component: Compiler | Version: 7.8.1-rc2 Resolution: | Keywords: Operating System: Windows | Architecture: x86_64 (amd64) Type of failure: Runtime crash | Difficulty: Unknown Test Case: | Blocked By: Blocking: | Related Tickets: ----------------------------------+---------------------------------- Comment (by awson): Yes, they are in RTS. More precise location is rts/sm/Evac.c line 390. Also I think this bug is triggered near foreign `memchr` call in function `elemIndex` from `Data.ByteString` module in `bytestring` package, which is inlined down to `lines` function from `Data.ByteString.Char8`. Also I checked this bug is not triggered if relevant modules from `bytestring` package are compiled with `-O` flag instead of `-O2`, hence this bug could be more ubiquitous if more applications code was compiled with `-O2`, perhaps. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8834#comment:23 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
