I wonder if this might have anything to do with the bug I just submitted for fftw3-3 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=619324That seems a 64bit problem not seen for 32bit.
That is a bug in your code, not in FFTW: you used INTEGER for plan variables, whereas the FFTW documentation explains that you should use INTEGER*8 so as to be wide enough to hold a pointer on both 32- and 64-bit machines.
