Bug ID: 2164233 Summary: FcCacheFini: Assertion `fcCacheChains[i] == NULL' failed. Product: Fedora Version: 37 Status: NEW Component: fontconfig Assignee: tagoh@redhat.com Reporter: byoungchan.lee@gmx.com QA Contact: extras-qa@fedoraproject.org CC: ajax@redhat.com, fonts-bugs@lists.fedoraproject.org, gnome-sig@lists.fedoraproject.org, i18n-bugs@lists.fedoraproject.org, mclasen@redhat.com, pnemade@redhat.com, rstrode@redhat.com, sandmann@redhat.com, tagoh@redhat.com Target Milestone: --- Classification: Fedora
Description of problem: When I try to run openttd, fontconfig crashes due to an assertion.
https://github.com/freedesktop/fontconfig/blob/2.14.1/src/fccache.c#L808
Version-Release number of selected component (if applicable):
$ rpm -qa | grep fontconfig fontconfig-2.14.1-2.fc37.x86_64 fontconfig-2.14.1-2.fc37.i686 fontconfig-devel-2.14.1-2.fc37.x86_64 fontconfig-debugsource-2.14.1-2.fc37.x86_64
$ rpm -qa | grep openttd openttd-opengfx-7.1-3.fc37.noarch openttd-12.2-4.fc37.x86_64
How reproducible: Run openttd
Steps to Reproduce: 1. 2. 3.
Actual results:
Crash
Expected results:
Game runs.
Additional info:
I'm not sure why assertions are enabled in fontconfig.

--- Comment #2 from Akira TAGOH tagoh@redhat.com --- Well, this is basically a memory-leak report in application. if it is 100% reproducible even after re-creating caches with fc-cache -f, it is a bug in openttd.
https://bugzilla.redhat.com/show_bug.cgi?id=2164233
--- Comment #3 from Akira TAGOH tagoh@redhat.com --- Try to run openttd with FC_DEBUG=16. you'll see more details then.
https://bugzilla.redhat.com/show_bug.cgi?id=2164233
--- Comment #4 from Byoungchan Lee byoungchan.lee@gmx.com --- I already uploaded the log with `FC_DEBUG=16`. It is included in the attached file (zip file). Anyway, I'll check out why the memory leak happened.
https://bugzilla.redhat.com/show_bug.cgi?id=2164233
--- Comment #5 from Akira TAGOH tagoh@redhat.com --- What I can say is that 12 of reference count is too much. there should definitely be a memory leak in openttd, possibly not freed FcPattern which have a reference to those caches. check around code where use FcFontList or FcFontMatch in openttd.
https://bugzilla.redhat.com/show_bug.cgi?id=2164233
--- Comment #7 from Byoungchan Lee byoungchan.lee@gmx.com --- If I modify openttd to force the use of X11, it works fine.
``` SDL_SetHint(SDL_HINT_VIDEODRIVER, "x11"); ```
It also works fine when I remove FcFini function calls from openttd.
I ran gdb to understand what happened with the fontconfig call, and I attached the result. When SDL2 uses Wayland, Pango is also used, which uses fontconfig. By the way, I discovered that Pango calls FcInit but not FcFini. Also, FcInit is called from a thread other than the main thread, whereas openttd proceeds with all fontconfig-related function call on the main thread.
https://bugzilla.redhat.com/show_bug.cgi?id=2164233
--- Comment #8 from Akira TAGOH tagoh@redhat.com --- I don't think gdb helps you to find out memory leaks. what you need to run with openttd should be valgrind.
https://bugzilla.redhat.com/show_bug.cgi?id=2164233
--- Comment #9 from Byoungchan Lee byoungchan.lee@gmx.com --- What I want to say is that Pango does not call FcFini, and openttd does not crash if Pango (and Wayland) is not used. If you think this is a Pango or openttd bug, please change the component.
