[alsa-devel] Crash when snd_pcm_open is called from a thread with "pulse" as playback
Hi folks,
I hope I post on the correct mail list... I've read somewhere that I should report bugs on a list, and not only on the Tracker. That's the aim of this message.
On all my Fedora 10 machines, whenever snd_pcm_open has been called from a pthread using "pulse" as playback then the program crashes when the thread terminates.
Crash in __nptl_deallocate_tsd
However, AFAIK, one should be able to call snd_pcm_open from a thread.
The full bug report is there, with a very simple sample code : https://bugtrack.alsa-project.org/alsa-bug/view.php?id=4426
I think this bug relates directly to alsa. I hope this report is useful.
Best- Nicolas

This appears to be a problem with Portaudio, right? My rough guess is something handling pthread in portaudio conflicting with pulseaudio, or any bug in the resource handling in portaudio...

Grr, forget it, now you posted a follow-up. Will check later.
