1 month ago I'll provide any data necessary. Some users report not getting this, so it might be the version of FFTW causing the issue.

1 month ago @bratpeki how consistent are you able to reproduce this issue?

1 month ago I am also on Arch Linux and use the same version of fftw. I cannot reproduce the crash if I start LMMS and then exit it immediately.

So it seems to be related to specific projects. I noticed that @bratpeki's output mentions fluidsynth?

1 month ago @michaelgregorius, Fluidsynth doesn't affect the segfault, that was just me using the session as I was using it when I first noticed the crash. @sakertooth, I can replicate it on each run of LMMS.
I believe the output is the same, but I'll provide it anyway.
