$1 = (GstMPEGStream *) 0x667e868
(gdb) p str->pad
$2 = (GstPad *) 0x1
(gdb) p type
$3 = 131074
(gdb) p str->type
$4 = 65535
(gdb) p mpeg_demux
$5 = (GstMPEGDemux *) 0x1de0410
(gdb) p mpeg_demux->audio_stream[stream_nr]
$6 = (GstMPEGStream *) 0x667e868

As you can see, str->pad points to an invalid address 0x1 and causes the crash.


Expected results:
Don't crash.


Does this happen every time?
Yes.
