custom CFLAGS

[mdew]

too my previous subject... err:module:map_image Could not map section .data, file probably truncated
the problem was my custom CFLAGS, which havent caused me too many problems...till lately ...(using wine)

export CFLAGS="-O3 -ffast-math -fthread-jumps -fcse-follow-jumps -mpentiumpro -march=pentiumpro -mcpu=i686 -malign-loops=2"
err:module:map_image Could not map section .data, file probably truncated
/usr/local/bin/wine: can't exec './xxx.exe': error=21

gcc 2.95.4-6 (Debian Sid) I havent tried gcc-3.0.1 yet, i trust gcc-2.95.4 still...give it another few versions before i'll look at gcc3.

in paticular is the use of -O3 over -O2, -O2 will work, -O3 will fail..why is that?
