I noticed LMMS segfault on exit.

I built LMMS with -DCMAKE_BUILD_TYPE=Debug and the GDB output is:

    Inferior 1 [process 116600] will be killed.

Quit anyway? (y or n) y
[peki@~]$

I opened a GIG and SF2 player player just to say something has been done in the project, the same thing happens when you just open and close LMMS.

The FFTW version is :

[peki@~]$ pacman -Q | grep fft
fftw 3.3.10-7

Expected Behaviour

No segfault.

Steps To Reproduce

Open LMMS. Optionally, do something. Close LMMS.
