Re: [Gimp-developer] Nightly Build of GIMP

[Jehan Pagès <jehan marmottard gmail com>]

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!
