#506: Crash when snd_pcm_open is called from a thread with "pulse" as playback
---------------------------+------------------------------------------------
Reporter: castagne | Owner: lennart
Type: defect | Status: new
Priority: high | Milestone: 0.9.15
Component: module-alsa-* | Severity: blocker
Keywords: thread alsa |
---------------------------+------------------------------------------------
On Fedora10, up to date, systematic crash using alsa lib.
pulseaudio 0.9.14 installed
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
I think this may really relate to pulseaudio
Sample code (very simple) included.
Back trace :
Program received signal SIGSEGV, Segmentation fault.
