Firefox 4 GDB backtrace

Hello,

I am trying to run the webGL demo at http://fractal.io/, however it crashes Firefox 4. The backtrace shows an assertion error in Mesa. Attached you will find the Firefox 4 backtrace and glxinfo.

Linux version: 2.6.37-12-generic (on Ubuntu 10.10)
Mesa version: 7.10.1~git20110215.cc1636b6-0ubuntu2 (from xorg-edgers PPA)
Firefox version: 4.0~b13~hg20110305r63332+nobinonly-0ubuntu1~umd2~maverick (from Mozilla Daily PPA)

Please let me know if you need more info.

Regards,
Cristi.

The value of INST_INDEX_BITS was recently increased so this might not be an issue any more (at least in this particular case).
Can you test with current Mesa from git?

I tried to run http://fractal.io with today's git version of mesa. Firefox 4 doesn't crash anymore, but now it hangs. Is there any info I can provide you with?

Unfortunately, the webgl part of the website seems to be gone, before anyone got a chance to apitrace it.
