Would you have used a 32-bit fftw library when you linked the program?
I made this mistake this before.
Both the 32- and 64-bit versions are installed on my Fedora Core 8
64-bit machine.
32-bit in /usr/lib/
64-bit in /usr/lib64/
Would it be this the reason for the segmentation fault?
Como dizia o A'lvaro de Campos, coitado,
a compilac,a~o e' um comi'cio dentro da alma. :)

Hi all
I've scourged the net for answers to no avail and the fftw project
seems to have grinded to a halt. Maybe someone has had this problem
and can throw some light.
I've coded a small program that reads a vorticity field, uses FFTW2
to send it from the physical to the spectral space and then computes
its energy spectrum. Everything works in my laptop (32 bit, Linux),
serial, threaded and mpi (using openmpi). In a 64 bit machine the mpi
version kaputs. Any thoughts?
