#696: segmentation fault in ./genprimopcode (x86_64)

Reporter: taral | Owner: simonmar

Severity: normal | Resolution:

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.
