Maybe related bug: https://bugs.freedesktop.org/show_bug.cgi?id=4705 This does reproduce with git version of Xft, c418dc7594f98359ae10815f62ee3efc0a511cf8 Created attachment 141026 [details] [review] Program to reproduce the bug Version with XSynchronize The last attachment also segfaults on Debian in FcConfigSubstituteWithPat, similarly to https://bugs.freedesktop.org/show_bug.cgi?id=107531 Hmm, it is not Debian vs non-Debian, the reason for segfault seems to be a rather complicated .fonts.conf. Without .fonts.conf I get the same X error. -- GitLab Migration Automatic Message -- This bug has been migrated to freedesktop.org's GitLab instance and has been closed from further activity.
