I try : $ gcc-4.4 -msse2 y.c -o y-4.4 $ ./y-4.4 ration=0.210000 ratio*10000000=2099999 same problem :( I watch asm code and : c code : double ratio = 0.21; asm code on 4.3 : fldl 0x8048580 fstpl -0x10(%ebp) asm code en 4.4 : fldl 0x8048590 fstpl 0x38(%esp) I think the is on 0x8048580 and 0x8048590 -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=42076
