#166: Various asserts in pulseaudio that result in mplayer crash
----------------------+-----------------------------------------------------
Reporter: Stax | Owner: lennart
Type: defect | Status: new
Priority: normal | Milestone:
Component: libpulse | Severity: major
Keywords: |
----------------------+-----------------------------------------------------
I'm getting errors which crash mplayer's ao_pulse sometimes. Both seem to
happen on stopping playback, making switching to next file in playlist
impossible. They are
mplayer: pulse/mainloop.c:287: mainloop_defer_enable: Assertion
`e->mainloop->n_enabled_defer_events > 0' failed.
It produces segfault and leaves core file, here is trace:
{{{

And another one:
mplayer: pulsecore/queue.c:67: pa_queue_free: Assertion `q->length == 0'
failed.
This one leaves no trace, just crashes, but reports that it happens in
uninit function, which looks like this:
{{{
static void uninit(int immed) {
if (stream && !immed) {
pa_threaded_mainloop_lock(mainloop);
waitop(pa_stream_drain(stream, success_cb, NULL));
}
if (mainloop)
pa_threaded_mainloop_stop(mainloop);
if (stream) {
pa_stream_disconnect(stream);
pa_stream_unref(stream);
stream = NULL;
}
if (context) {
pa_context_disconnect(context);
pa_context_unref(context);
context = NULL;
}
if (mainloop) {
pa_threaded_mainloop_free(mainloop);
mainloop = NULL;
}
}
}}}
