Public bug reported:
Using Linux Mint Maya 64-bit (based on Ubuntu 12.04) and
libgstreamermm-0.10-2 version 0.10.9-1, a call to
Gst::PlayBin2::create() causes the application to freeze or crash. A
glib error message in free() or realloc() is usually printed.
Minimal example:
#include <gstreamermm.h>
int main()
{
Gst::init();
Gst::PlayBin2::create();
}
$ g++ -g main.cpp `pkg-config gstreamermm-0.10 --libs` `pkg-config --cflags
gstreamermm-0.10`
$ ./a.out
*** glibc detected *** ./a.out: free(): invalid next size (normal):
0x0000000002198c00 ***
^C
$
Attached is the valgrind output for the minimal example and two backtraces from
when the application actually crashed instead of simply freezing (from an
actual application that uses gstreamermm).
When running the application with valgrind, the same invalid write as in the
minimal example happens, however the track actually plays for a fraction of a
second. After hitting pause/continue a few dozen times, all following tracks
seem to play properly. Without valgrind, the application freezes or crashes
without exception.
