When running clutter's new fbo test program, I systematically see the following crash of the server: Program received signal SIGSEGV, Segmentation fault.

I'm using git HEAD (as of today 4th at 8AM GST) for Xserver, intel DDX, drm and mesa. The test program is test-fbo from clutter HEAD (http://svn.o-hand.com/repos/clutter/trunk)
Please attach Xorg.0.log.

The crash is not related to the fbo test, most of clutter's test suite result in that crash.
I'm only seeing the hardware hang (which is what that crash is a result of) with the fbo test. For other clutter tests, only test-shader fails to draw as expected (bug #14416), and test-textures gets OOM-killed though I haven't tracked down who's responsible for that.
I updated today to git tip of everything, I am still seeing the same lockups. I do see the lockup with at least test-scale, test-actor, test-entry. That's all the ones I have tried. The lockup sometimes does not happen immediatly, sometimes after a few frames.
I think running them with CLUTTER_VBLANK=none solves the issue. Maybe it relates to the recent problem found in the driver when apps sync on vblank (can't find the bug number)?
Johan, does this still exist? I'm CCing Shuang to see if he could reproduce with the latest code.
