Segmentation Faults happen sometimes - Not reproducible

[AI-Guru]

Hi!

I sometime encounter segmentation faults:

Fatal Python error: pygame_parachute: (pygame parachute) Segmentation Fault
Python runtime state: initialized

  warnings.warn('resource_tracker: There appear to be %d '

This is impossible to reproduce.

Any ideas?

Did you try to reproduce but it only happened once? If you manage to reproduce it please share a minimal reproducible example. There's a chance it's related to this singleton https://github.com/DBraun/DawDreamer/blob/d0d97e421241a66ffd3e0cb78d99174d7d8f61d6/Source/PluginProcessor.cpp#L69

Can you try version 0.6.16? There's a possible fix.

Wow! Thanks! I will keep you updated.

Hi! I did a quick check today. I upgraded to 0.6.16. I immediately ran into a new problem.

It seems that synth.load_state(synth_state) does not work anymore.

I downgraded to 0.6.15.

I did another test with 0.6.16. The semaphore problem is still there:

UserWarning: resource_tracker: There appear to be 1 leaked semaphore objects to clean up at shutdown
  warnings.warn('resource_tracker: There appear to be %d '

Hi @DBraun! I believe I have a minimal script here. And it causes segmentation faults. Please suggest I way to share a zip file with you.
