It will fail with -msse:

I got

FAIL: gcc.dg/conv-1.c (internal compiler error)
FAIL: gcc.dg/conv-1.c (test for excess errors)
FAIL: gcc.dg/Wconversion-real-integer.c (internal compiler error)
FAIL: gcc.dg/Wconversion-real-integer.c (test for excess errors)

when I added -march=core2. They are the same bug as this one.
