Description Paul Menzel 2013-06-01 15:03:24 UTC

Using Debian Sid/unstable, Totem 3.4.2 crashes, when playing more than two songs in an infinite loop and it jumps from the last to the first.

	$ LANG=C totem /usr/share/sounds/gnome/default/alerts/sonar.ogg /usr/share/sounds/gnome/default/alerts/glass.ogg

I was told this is most probably a memory leak.

I’ll attach the Valgrind output. But I could not find anything related to Totem in there.

G_SLICE=always-malloc G_DEBUG=gc-friendly valgrind --tool=memcheck --leak-check=full --leak-resolution=high --num-callers=20 --log-file=/tmp/20130601--totem.vgdump --track-origins=yes totem

Running it under Valgrind 3.8.1-3, it does not crash.

The following message is shown after every jump from the last to the first song.

    (totem:25803): Gtk-CRITICAL **: gtk_list_store_get_path: assertion `iter->stamp == priv->stamp' failed

Please find the output of

    $ G_SLICE=always-malloc G_DEBUG=gc-friendly valgrind --tool=memcheck --leak-check=full --leak-resolution=high --num-callers=20 --log-file=/tmp/20130601--totem.vgdump --track-origins=yes totem /usr/share/sounds/gnome/default/alerts/sonar.ogg /usr/share/sounds/gnome/default/alerts/glass.ogg

attached. Unfortunately I had to compress it due to the size limit being 1.6 MB.

Comment 2 Tim-Philipp Müller 2013-06-01 17:06:24 UTC

It's probably best to remove the --leak-check=full if you want to debug a crash, it is not really useful for that, just adds noise in the log at the end.

Since you get these criticals, you should probably first look at where these criticals come from. You can do that by running totem in gdb like this:

 $ G_DEBUG=fatal_warnings gdb --args totem /usr/share/sounds/gnome/default/alerts/sonar.ogg /usr/share/sounds/gnome/default/alerts/glass.ogg

and then

  (gdb) bt

 when it crashes.

The critical is probably caused by either passing an iter from another list/tree model to gtk_list_store_get_path(), or an uninitialised iter (but in that case you should have seen that in valgrind).

Thanks for the information.

I think, I’ve seen these before without any crashes.

The clutter-errors are printed long before the crash happens (monitored with `tail -f …`).

So it looks like, Valgrind changes the memory allocation(?) in such a way, that the crash is not reproducible there.

You could try G_SLICE=debug-blocks instead of valgrind.

Thanks for your suggestion about `G_SLICE=debug-blocks` [1]. I ran it several times.

	$ LANG=C G_SLICE=debug-blocks totem /usr/share/sounds/gnome/default/alerts/sonar.ogg /usr/share/sounds/gnome/default/alerts/glass.ogg

Interestingly above, it ran through correct the first time (jump from last to first), but failed the second. No additional error messages are printed here. Trying the same command again, it crashes after the first jump from last to first.

No additional error message. The Gtk-Critical message is missing though.

	*** Error in `totem': malloc(): smallbin double linked list corrupted: 0x0a1ba020 ***

Not sure, what is causing it, but we get an additional warning about a corrupted linked list.

So I assume, this is indeed some kind of memory leak? But why did Valgrind not find those?

Comment 8 Paul Menzel 2013-06-02 12:02:55 UTC

Debian developer Emilio responded, that it might be a problem with newer GLib and GObject introspection.

So please ignore this issue, as it looks like a Debian packaging problem. I am going to close this bug, after this theory has been proved to be well founded.
