There was the compiler change in there, though. The mis-optimization may
have been beneficial in some corner case in the Radeon driver. (handwave,

I'll try that, but as I have no reliable way to reproduce the problem, I
will only be able to provide a guess, and that only after several days.
GL wasn't ever in use at the time of the crashes, though. (I'll go back
to -5 at the same time, to increase the odds of provoking the bug if it
isn't due to DRI.)

It did not seem useful to submit a bug report with this level of vagueness
about the cause. If you would prefer a bug report I can certainly file
one.
