[Bug 1436162] Re: [pulsesink] abort at pthread_mutex_unlock(&m->mutex) == 0' failed at pulsecore/mutex-posix.c:118, function pa_mutex_unlock() with libc 2.21
This bug was fixed in the package glibc - 2.21-0ubuntu4
---------------
glibc (2.21-0ubuntu4) vivid; urgency=medium
* debian/patches/arm/local-arm-futex.diff: Lie about the minimum
kernel support for futex_atomic_cmpxchg_inatomic to restore the
previous state and make pulsesink happier on ARM (LP: #1436162)
* debian/debhelper.in/libc.preinst: Wipe ld.so.cache on upgrades.

Bug description:
current build number: 146
device name: m75
channel: ubuntu-touch/vivid-proposed

version version: 146
After libc 2.21 landed, pulsesink fails constantly when pausing or
seeking the active pipeline.
Abort message:
Assertion 'pthread_mutex_unlock(&m->mutex) == 0' failed at pulsecore/mutex-posix.c:118, function pa_mutex_unlock(). Aborting.
This is basically happens when it tries to unlock a mutex that is
already unlocked.
This issue doesn't happen with libc 2.19.
To reproduce the issue:
GST_DEBUG=*pulse*:5 gst-launch-1.0 playbin uri=file:///tmp/foobar.mp3
Then when playing, just hit control+c, which will then pause the
pipeline, causing the crash. The crash happens with most of the times
you pause or seek the pipeline.
