From the crash dump, I see that the crash happens in fontconfig's FcConfigParseAndLoad function, i.e. when the system fonts.conf is read. I can reproduce the crash with the following minimal example: ---- #include </usr/include/fontconfig/fontconfig.h> const FcChar8* filename = "/home/mirkoh/fontconfig-test/fonts.conf"; FcConfig* config; int main(){ FcConfigParseAndLoad(config, filename, FcTrue); } ---- The fonts.conf file used here is also absolutely minimal: ---- <?xml version="1.0"?> <!DOCTYPE fontconfig SYSTEM "fonts.dtd"> <fontconfig> </fontconfig> ---- (Get me right. It first happened with my system fonts.conf, which is not empty. In order to find out whether a specific entry lead to the crash, I deleted entry after entry, ultimately reaching the file above, and always FcConfigParseAndLoad crashes. I have no idea how to go on from here.
