Binaries are definitely in sync:
$ ll -gG /usr/bin/fc-* /usr/lib64/libfontconfig.so.1.0.4
-rwxr-xr-x 1 14176 jan 19 21:56 /usr/bin/fc-cache
-rwxr-xr-x 1 32176 jan 19 21:56 /usr/bin/fc-cat
-rwxr-xr-x 1 11096 jan 19 21:56 /usr/bin/fc-list
-rwxr-xr-x 1 11336 jan 19 21:56 /usr/bin/fc-match
-rwxr-xr-x 1 260840 jan 19 21:56 /usr/lib64/libfontconfig.so.1.0.4
Today I also got the same output from fc-cat on my ~/.fonts.cache-2 and
it is much larger than the system cache files.

The valgrind output from cairo cvs is gigantic, so I haven't had the
time to track them down, but I've attached the output of
# valgrind --leak-check=full fc-cache -sfv > fc-cache-valgrind 2>&1
Note the warnings about write()ing uninitialized buffers to the cache.
