This is good info.  It's blowing up libfftw3f, the FFTW code.
Haven't ever seen that failure.

I'd suggest building fftw from source (www.fftw.org) using the
--enable-single --enable-sse --enable-shared configure options, and
then after it's built make sure that its "make check" passes.

If this fixes the problem, there may be a problem with the libfftw3f
library distributed with FC3.
