Bugzilla Bug 84034

The output is shown below. The spice deck does not matter. Spice appears to
read the first line of the input deck and then catch a seg fault.

I had a similar problem on a p4 using C(XX)FLAGS of "-O3 -march=pentium4
-fomit-frame-pointer -pipe" but when I went to "-O2 -march=pentium4 -pipe" it
no longer seg faults.

(I realize that these are different architectures but SPICE may be more picky
about compile time flags than assumed.)

I got the same with my pentium4 and the following flags:
CFLAGS="-O3 -march=pentium4 -fomit-frame-pointer -pipe"

Lowering them to "-O2" gives the same error.

removing "-Ox" at all corrects it.

Maybe a filter could be added to the ebuild in order to remove the "-Ox" flag
Sure it is not AMD64 specific, but, at least, x86.

Fixed in CVS, thanks for reporting.
