OK, so I'm obviously able to reproduce the use-after-free. Like I said, this

Oh, I'm sure (can't right now, will try tonight). But I doubt it's the source
of the bug. The glxtest program doesn't appear to hang. Memory is

Looks like a NouVeau is triggered by Mozilla Firefox trunk code.
I opened a bug on mozilla bugtracker,

Even if I find a "dirty workaround", valgrind logs are showing a NouVeau driver

Hi Benoit Jacob
Can you attach the output of glxinfo and dmesg after you've come across this
issue ? Do you have a link to a build we can reuse ?

I have also asked the original reporter to share his glxinfo output and details
about his setup. You might want to CC yourself on the mozilla bug.
