hi,

application using fontconfig (and that basically whole of gnome) get
several valgrind warnings as fontconfig uses a kind of hackish
addressing scheme. Fontconfig uses mmapped caches and for this absolute
pointers are useless. Thus they use the lower bit to signal that the
pointer is relative (if bit==1).
Now I wonder if there is a way to tell valgrind about it (client
requests [1]). At least could client-requests be used to blacklist the
memory-range from being scanned/monitored?
