I'd bet that you're calling MPI routines directly from your Fortran code somewhere, and fftw is a red herring... When calling MPI routines directly from your Fortran code, be very, very careful about the arguments being passed. Many MPI routines stuff a pointer in a "large enough" integer, but some of the MPI/Fortran "header" files make too many assumptions about the particular compiler and flags in use. You might want to use the ISO_C_BINDING module and the BIND(C, NAME="...") gizmos to declare the specific routines you're using.
