I saw and applied a FFTW3 patch - just to check that it can be applied cleanly.
The patch applies cleanly, but, as I have just written in another reply, the
problem occurs before the FFTW2/FFTW3 piece of code.
If anybody is interested, the patch was found as
http://sourceforge.net/tracker/index.php?func=detail&aid=1055258&group_id=55736&atid=478072 ->
http://sourceforge.net/tracker/download.php?group_id=55736&atid=478072&file_id=158343&aid=1055258
.
Thanks,
Sergei.
