A strangest thing is going on. With the following program #include <fontconfig/fontconfig.h> int main( int argc, char **argv ) { FcConfig *fc = FcInitLoadConfigAndFonts(); FcFini(); return( 0 ); } I get the following output: test-fontconfig: fccache.c:412: FcCacheFini: Assertion `fcCacheChains[i] == ((void *)0)'' failed. Aborted I have tried the test program with 2.4.1 and 2.4.2 versions of the library with 32 and 64 bit x86 machines.
