#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): Replying to [comment:17 simonmar]:
I'm surprised that the change to `isTrivial` all by itself causes this failure. That must mean that there was something wrong with the code before the "bad patch", because the change to `isTrivial` should be safe.
It probably would worth to add that reverting `isTrivial` only does not help either. I. e. `isTrivial` all by itself broke things as they were before that bad commit, but changing *only* `isTrivial` to it's pre-commit state does not help either. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8834#comment:19 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
