Description Ray Strode [halfline] 2006-08-21 02:49:08 UTC 
(downstream report is http://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=202152)

Fontconfig currently reserves 5 bytes right now to encode the system page size
into a serial string.  One of those bytes is always " " (space), leaving 4 bytes
for the actual hex encoded value.  The problem is 4 bytes is 1 bit too small for
encoding the page size on 64k page systems and so on these systems teh serial
string buffer overflows.

I posted a message about this problem here:
