Thank you for your quick reply.

I managed to do a short program that expose the problem, and copied source on Pastebin:

Program will create a 100 pixel square image in light pink color, on a png file with alpha channel.
It work on Linux, Windows and Mac OSX 10.6.8.

In OSX 10.9.4 it creates a fully transparent image with no color at all.

Thank you.
