--- Comment #40 from Chris Wilson <chris at chris-wilson.co.uk> ---
The only way I can see it crash like that is if ScrnInfo->pScreen is stale.
I've reviewed all the code and cannot see how that would be possible. Anyway,
I've thrown in a couple more assertions to test that hypothesis:

commit d4164de5ccb82068e2858a90b2cd44eef82b6037

    sna: Assert that the ScrnInfo and ScreenPtr relationship is correct

Can you please try to reproduce again with --enable-debug[=full] and see it
hits those assertions?
