#13617: Segfault in Windows GHCi involving C code compiled with -O4 --------------------------------+---------------------------------------- Reporter: RyanGlScott | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: Component: GHCi | Version: 8.0.2 Resolution: | Keywords: Operating System: Windows | Architecture: Unknown/Multiple Type of failure: GHCi crash | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | --------------------------------+---------------------------------------- Comment (by RyanGlScott): As Phyx- pointed out to me, `-O4` is just an alias for `-O3` in `gcc` and `clang`, so the issue is really with `-O3`. I've confirmed that setting `gcc-options: -O3` also triggers this segfault, but not with `gcc-options: -O2`. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13617#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
