#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:14 jstolarek]:
So this works:
{{{ isTrivial :: CmmExpr -> Bool isTrivial (CmmReg _) = True isTrivial _ = False }}}
but this doesn't:
{{{ isTrivial :: CmmExpr -> Bool isTrivial (CmmReg (CmmLocal _)) = True isTrivial _ = False }}}
Conversely. The first does not work, the second works. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8834#comment:15 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
