It certainly doesn't happen for me on any of the machines I work with,
but it wouldn't compile as-is for me, so I exchanged the FPU setting
with a simpler
asm("fldcw %0": :"m" (0));
which should do the equivalent (ie unmask divide by zero errors). Does
that make a difference for you?
Can you try to figure out where it started happening? Ie try test9 and
back too, to figure out what might be bringing it on...
I sure as hell hope this isn't an Athlon issue. Can other people try
the test-program and see if we have a pattern (ie "it happens only on
Athlons", or "Linus is on drugs and it happens for everybody else").
Thanks,
Linus
