--- Comment #31 from Jaroslav Škarvada <jskarvad at redhat.com> ---
(In reply to Wolfgang Ulbrich from comment #30)
NP. The second patch is also more robust. Try the stress reproducer from
comment 17 and comment 18, the "proposed fix" should withstand the test without
crash at least.

BTW I am still running the patched cairo on production machines without
problem.

I wonder what we did wrong. There is reproducer, analysis of the problem and
patch.
