I can't reproduce this using gcc-3.3-20041006.
I guess I'll try prerelease-3.3.5-20040914 now,
is that what you used?

Are you using any patches?

Great...

The kernel FP emulation is supposed to, but it's
pretty slow, and people who want fast floating point
often turn on one of the soft floating point options.
You should stick with kernel FP emulation if it works
well for you.
