SubjectRE: Question on SIGFPE
Date
From
Hi Mr Johnson,
I used it and was able to compile, run. Well it still was
crashing. We are using a mips processor. I am sorry I didn't mention
about this. Thanks a lot for the help.

Regards
Sreeram

Yes. I just looked on a RH-9 system. The stuff I referenced
was probably before there was a Red Hat!

I don't like that MACRO. Hopefully it works. It accesses memory that may
not exist if you do _FPU_SETCW(_FPU_DEFAULT).

For safety do:

fpu_control_t cw = _FPU_DEFAULT;
_FPU_SETCW(cw);


Cheers,
