--- Comment #2 from draymond at foxvalley.net ---
I have confirmed that the change submitted below suppresses the crash during my
test case:

http://cgit.freedesktop.org/cairo/commit/?id=5c82d91a5e15d29b1489dcb413b24ee7fdf59934

This change was pulled into cairo 1.14.2.

However, the original author of that patch (ilia.softway at gmail.com) has
expressed doubts that this change fully fixes the problem and he is now using
an additional patch to cell_list_add_subspan() in cairo-tor_scan-converter.c.

Therefore, I think it is best to leave this bug open until the root cause is
fully understood.
