Thanks for that hint - got it running now without those flags. :)
Hmm. Why?
What is wrong with the code that SSE breaks?

Nah,
while experimenting i tried to alter the 32bit flags with ccmake
(using -march=i686, -O2 or removing the -msse2 because i wasn't sure if
my AthlonXP CPU supports it) which led to even more problems. So i think
they are in effect, and I stayed with the flags ccmake determined by
itself, "-O3 - march=native -msse -msse2 -mfpmath=sse -ffast-math
-fomit-frame-pointer"
Probably is it. Take out -msse and -msse2 and -mfpmath=sse, and see
what it does.
