This commit seems quite old (4 years old).

I've tried again in my own setup:

- OpenGL renderer string: Mesa DRI Intel(R) Ivybridge Desktop
- OpenGL core profile version string: 3.3 (Core Profile) Mesa 13.1.0-devel (git-9f150ff)
- VirtualGL: 2.4.1


It worked fine: no hangs nor crashes.

Sorry no one ever investigated your bug.

Please test a new version of Mesa (12 or 13) and mark as REOPENED
if you can reproduce and RESOLVED/* if you cannot reproduce.

Dear Reporter,

This Mesa bug has been in the "NEEDINFO" status for over 60 days. I am closing this bug based on lack of response but feel free to reopen if resolution is still needed. Please ensure you're supplying the correct information as requested.

Thank you.
