I can confirm fontconfig erases bad global cache files.

But I found a way to cause fontconfig to never update cache correctly
with the following test case :
-clean your cache completely : rm -f /var/cache/fontconfig/*
-run fc-cache -v to get a consistent cache
-put the attached old fonts.cache-2 (before cache was moved
to /var/cache/fontconfig) in /usr/share/fonts/ttf/big5
-run fc-cache -v => cache is updated for this directory
-run fc-cache -v again => cache is updated AGAIN for this directory and
is growing (check in /var/cache/fontconfig..)
-remove fonts.cache-2 from the directory
-run fc-cache -v several time : each time, cache is updated and grow.

I've attached the file to put in big5 directory as well as the broken
cache which is generated in /var/cache/fontconfig and the good one.

This problem is not visible when using non-root applications because
missing cache will be stored in ~/.fonts.cache-2 and won't get updated.
