#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 simonmar): I believe `mingw32_HOST_OS` is defined on 64-bit Windows. The full platform name is `x86_64-unknown-mingw32`, i.e. `mingw32` is the OS. You can test this with `ghc --info` on your 64-bit Windows GHC. If `memchr` is clobbering allegedly callee-saves registers, then either `memchr` is wrong, or our idea of what is callee-saves is wrong. Which is it? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8834#comment:58 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
