#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.
