--- Comment #28 from Alexander Cherepanov <ch3root at openwall dot com> ---
The -funsafe-math-optimizations option has a similar problem (on all
processors, I assume) -- I've just filed pr93806 for it. I guess unstable FP
results are essential for this mode but integers computed from FPs should be
somehow guarded from instability.

I don't know if anybody cares about -funsafe-math-optimizations but if it's
fixed then x87 will get this improvement for free:-)
