Description Stephane Loeuillet 2004-12-18 14:33:54 UTC 
i used the 12-Toxicity.mpc file from ronald's FTP (in /musepack)

it is an APE tagged musepack file, so to play it, i tried the following pipeline :
filesrc location=12-Toxicity.mpc ! apedemux ! musepackdec ! alsasink

the crash happens just after gst-launch -v said :
/pipeline0/filesrc0.src: active = FALSE
(and sounds stop a few seconds after)

it played the file fine, but at the end, it segfaulted, got a backtrace :

Looks just like the stack trace in bug 152702, though I hesitate to mark it as a
duplicate since that bug was closed...

Elijah is right, it is the same bug.

the only differences are :
152702 : generated via a new experimental gst-player which is now deprecated
161624 : generated via a simple gst-launch pipeline
=> simplier to reproduce, less elements involved

my alsa-lib is also compiled with debug info/not stripped

It's also reproduceable using osssink:

Program received signal SIGSEGV, Segmentation fault.
