[cairo] Fwd: Cairo 1.14 error on OS X 10.10.3 Yosemite

[suzuki toshiya]

Hi,

I could reproduce the issue, and I guess it could be
fixed by upgrading the latest git (or future release
of 1.14.3). My results are:
http://gyvern.ipc.hiroshima-u.ac.jp/~mpsuzuki/cooling-scenarios_1.14.1.pdf (good)
http://gyvern.ipc.hiroshima-u.ac.jp/~mpsuzuki/cooling-scenarios_1.14.2.pdf (bad)
http://gyvern.ipc.hiroshima-u.ac.jp/~mpsuzuki/cooling-scenarios_1.14.3.pdf (good)
At present, I'm not sure if 1.14.3 should be released
as it is in git head, or, 1.14.3 should prioritize older
Mac OS X functions as far as they are available.
If you have your comment, please post...

Regards,
mpsuzuki
