Stacktrack of crash

We're getting reports in Ubuntu 15.04 [1] [2] of crashes in the Intel driver. This seems to have occurred during the switch from 2.99.917 to a git snapshot from 8th August 2015.

I'm not able to reproduce this issue locally and inspection of the code has't made it clear to me if any changes since then have fixed the issue. Raising here in case someone recognises the problem and the commit that may have fixed it.

That crash was fixed before then. Code inspection shows that it should be impossible to get that stacktrace now - I am dubious about the reports.

You were correct - the crash reports are coming from users who have not updated in the last three months. Sorry for the noise.
