Crash in pfft_plan_dft about pfft HOT 6 OPEN

Just to add that an equivalent in pure FFTW3 is running properly. I am not sure if this is a regression, but I think my program used to work with this transform before.

Thanks for the report. I checked it with the current master branch and
it did not crash. Did you install FFTW-3.3.4 with my install scripts
(including my performance patches), or did you use the plain FFTW-3.3.4?
Would be great if you could test it with the current master or at least
version 1.0.8. Does it also crash with less processes?

I used stock FFTW 3.3.4. One of the computers has pfft commit cd46191. It doesn't crash with less processes.

Now, I got the same segfault in FFTWs internal plan free with the
non-patched version. Looks like a bug in FFTW-MPI. I have to dig deeper
into the code for locating the problem.

This segfault was caused by a double free within FFTW-MPI. I fixed it in commit 9831bbd of the official FFTW repository on Github. The bugfix is already included in FFTW-3.3.5.
Please verify if the problem is solved for you with this version of FFTW.

This is the link to the bugfix.
