Hi folks, I'd need the help of some alsa developpers regarding the bug report :https://bugtrack.alsa-project.org/alsa-bug/view.php?id=4426 We've made a few progress on it, but we are stuck again. Basically, it seems that calling snd_config_update_free_global() from apthread causes the program to crash when the thread terminates. Questions are: Should config_update_free_global NOT be called from a thread ? In other words, is the following code valid (though dumb :=)) ?Or is there some reason for it to crash ? **********************************#include <pthread.h>#include <alsa/asoundlib.h>void * threadWork(void *arg) { snd_pcm_t *playback_handle; if (snd_pcm_open (&playback_handle, "default",SND_PCM_STREAM_PLAYBACK, 0) < 0) fprintf (stderr, "error\n"; snd_pcm_close(playback_handle); snd_config_update_free_global(); return NULL;}int main() { pthread_attr_t attr; pthread_attr_init(&attr); pthread_t threadid; pthread_create( &threadid, &attr, threadWork, NULL); return EXIT_SUCCESS;}********************************** I thank you much, Nicolas ---------------------------- Message original ----------------------------Objet: Crash when snd_pcm_open is called from a thread with "pulse" as playbackDe: castagne@xxxxxxxxxxx: Mer 4 mars 2009 8:20À: alsa-devel@xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx 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 onthe Tracker. That's the aim of this message. On all my Fedora 10 machines,whenever snd_pcm_openhas been called from a pthread using "pulse" as playbackthen 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.
