gcc aborts when both -march=athlon-xp -O2 are set:

/tmp$ ~/local/gcc-3.1/bin/gcc -march=athlon-xp -O2 -c t.c
t.c: In function `FFT':
t.c:48: Internal compiler error in ix86_secondary_memory_needed, at config/i386/i386.c:12251
>How-To-Repeat:
run `gcc -march=athlon-xp -O2 -c t.c' on the attached file
>Fix:
removing either one of two options -march=athlon-xp -O2 
avoids the crash
