#696: segmentation fault in ./genprimopcode (x86_64) -+-- Reporter: taral | Owner: simonmar Type: bug | Status: new Priority: normal | Milestone: 6.4.2 Component: Compiler (NCG) |Version: 6.4.1 Severity: normal | Resolution: Keywords: | Os: Linux Difficulty: Unknown | Architecture: x86_64 (amd64) -+-- Comment (by simonmar): null.s looks like it is unregisterised, whereas null.fasm.s is registerised. This would explain the crash: if the default RTS is unregisterised, linking registerised code against it will fail. So I guess your Debian build of GHC 6.4.1 is unregisterised. This is something you should probably look into - there's no reason to have an unregisterised build of 6.4.1 for x86_64, registerised works fine and is a lot faster (and -fasm works). It is usual to disable the native code generator for a registerised build. I guess the Debian folks didn't do this. I'll look into providing more safety checks in GHC to make sure you get a sensible error message rather than a crash in the future. -- Ticket URL: http://cvs.haskell.org/trac/ghc/ticket/696 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler___ Glasgow-haskell-bugs mailing list Glasgow-haskell-bugs@haskell.org http://www.haskell.org/mailman/listinfo/glasgow-haskell-bugs
