New issue 9245 by [email protected]: Fontconfig memory leaks on Linux?
http://code.google.com/p/chromium/issues/detail?id=9245

There seem to be memory leaks in fontconfig,
even after calling FcConfigDestroy(foo) and FcFini(),
e.g.

442 bytes in 6 blocks are definitely lost in loss record 324 of 406
    at realloc trunk/coregrind/m_replacemalloc/vg_replace_malloc.c:456
    by (within /usr/lib32/libfontconfig.so.1.3.0)
    by (within /usr/lib32/libfontconfig.so.1.3.0)
    by FcFreeTypeCharSetAndSpacing (in /usr/lib32/libfontconfig.so.1.3.0)
    by FcFreeTypeQueryFace (in /usr/lib32/libfontconfig.so.1.3.0)
    by FcFreeTypeQuery (in /usr/lib32/libfontconfig.so.1.3.0)
    by (within /usr/lib32/libfontconfig.so.1.3.0)
    by FcConfigAppFontAddFile (in /usr/lib32/libfontconfig.so.1.3.0)
    by TestShell::InitializeTestShell(bool)
webkit/tools/test_shell/test_shell_gtk.cc:152

Also same leak with calloc instead of realloc.

(More might be lurking, e.g.

And there might be some false positives?  See
