[PD-dev] Pd hangs on exit on macOS

[Dan Wilcox]

Is anyone noticing that the Pd core seems to hang on macOS? You can close the GUI but sometimes the "pd" core process spins in the background sucking up CPU or the GUI freezes on exit as well?

It seems to be spinning in the port audio ring buffer s_audio_paring.c line 130. Both index and rbuf->bufferSize are 0 and it's stuck in the while loop, although this is after sys_close audio should have happened. Maybe it's a thread race condition? I don't remember this happening before macOS 101.4 so I wonder if it's something lower level as there has been the general push towards AudioUnit V3. Ugg.
