#8834: 64-bit windows cabal.exe segfaults in GC ----------------------------------+---------------------------------- Reporter: awson | Owner: jstolarek 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 simonpj): Austin will try: * Re-applying the `CmmSink` patch * Adding R3 and R4 to the caller-saves register for 64-bit That would be a better fix, because if they really are caller-saves then reverting `CmmSink` won't necessarily cure everything. Still needs more investigation for the ultimate cause. Simon -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8834#comment:62 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
