Hi, thanks, I'll try to recompile cairo with these options and see if I can reproduce the crash. Note that the crash is fixed by just changing the cairo and libpng dll (initially I had to change libpng because I tested with older versions, but now I could try only by changing cairo indeed), so I don't think that pixman may be the cause. But of course you may try. There may be some unexpected side-effect; we never know. Anyway yes let's continue on the tracker from now on!
