Hi Marcus,
In the past we've seen some core dumps from FFTW. I don't recall
exactly what the conditions were, but it seemed to depend on the
compiler version.
You might want to try building FFTW from source using the
./configure --enable-single --enable-shared
options. Your problem may have something to do with --enable-sse and/or
changes in compilers, etc.
