Comment (by jdemeyer):
Replying to [comment:7 vbraun]:
> * Even besides FMA there is always the possibility of 80-bit x87
instructions messing things up
With x87, it is reasonable to assume that the whole imaginary part will be
evaluated with 80 bits, so there won't be numerical noise either (see also
the successful i386 buildbot reports).
