--- Comment #32 from Benoit Jacob <bjacob at mozilla.com> ---
...note that the log attached by Frederic in comment 30 also has a stack to
where this pointer was free'd --- we have a use-after-free bug here!

This was obtained by Frederic by running the glxtest program attached in
comment 2 here, in valgrind:

  valgrind --track-origins=yes ./glxtest

I hope that Nouveau developers here can reproduce this easily!
