Preamble: I'm not using fedora-mingw directly, but a port of it. I checked for the presence of eventual differences that could be the culprit but I did not find anything relevant: I think this problem should be present also under fedora. Description of problem: A program I'm developing (http://sourceforge.net/projects/ntdisp/ the relevant installer being under testing/ntdisp-0.5.0-6-win32.exe) crashed at start-up under wine with an assertion failure. I tested gtk3-demo and it crashes too with the same assertion, but after a click on the tree view. Steps to Reproduce: $ wine /path/to/gtk3-demo.exe ... and click on a test in the tree view. Actual results: > Assertion failed! > > Program: Z:\usr\i686-w64-mingw32\bin\gtk3-demo.exe > File: /home/aur/archlinux/fedora-mingw-w64-cairo/src/cairo-1.12.14/src/cairo-surface.c, Line 930 > > Expression: CAIRO_REFERENCE_COUNT_HAS_REFERENCE (&surface->ref_count) > > abnormal program termination Expected results: A shiny test running flawlessly. Additional info: Upstream bug: https://bugs.freedesktop.org/show_bug.cgi?id=63787 GNOME report: https://bugzilla.gnome.org/show_bug.cgi?id=704540 Proposed patch: http://bugs.freedesktop.org/attachment.cgi?id=82797 I tested the proposed patch (http://github.com/ntd/aur-fedora-mingw/commit/8a317cd709b61d9bef1c9d7cb7d7647738c560f5) and it works fine.
Thanks for the patch! I also got hit by this bug, but wasn't aware of your patch yet. I'll apply it right away. This issue should be rawhide-only (as I've only seen it occur in combination with the latest unstable mingw-gtk3)

The patch is by Michael Henning by the way ;) > I'll apply it right away. > This issue should be rawhide-only (as I've only seen it occur in combination > with the latest unstable mingw-gtk3) I can confirm this problem appeared somewhere on 3.9 development branch.
The patch is applied in mingw-cairo-1.12.14-5.fc20 https://koji.fedoraproject.org/koji/buildinfo?buildID=453920
