--- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
That is the effect of excess precision on i387, see PR333.
You can either use -msse2 -mfpmath=sse if your CPU is capable of SSE2,
or -fexcess-precision=standard for slower, but guaranteed excess precision
according to target macros, or -ffloat-store for even slower behavior.
