Description Scott Zuk 2007-04-17 02:43:00 UTC 
Steps to reproduce:
I have a pipeline that uses an alsasrc to read audio from the mic and pass it through an audioconvert and audioresample element and then into an adder.  I have a second bin that consists of filesrc, decodebin, audioconvert and audioresample elements and that feeds into another sink of the adder.  The adder src outputs to an alsasink.  I use this pipline to be able to play an audio file at any time and have it mixed with the microphone data.  I will attach a test program that repeatedly plays a file while mixing it with the mic.  When I use any audio file (wav or vorbis tested), the program will eventually cause a segfault that seems to always be related to audioresample_buffer_queue_pull in audioresample.

Comment 3 Tim-Philipp Müller 2007-04-17 06:54:02 UTC 
Looks like another manifestation of bug #420106 to me (race condition when shutting down).
Comment 4 Tim-Philipp Müller 2007-04-21 14:04:13 UTC 
Fairly sure this is a duplicate of #420106, since the test case I made for that crashed exactly the same way. Your test program also runs fine for me. Please re-open if you still have this problem with an up-to-date GStreamer core/-base CVS.
