xfstt core dumps at times, especially when trying to serve the
regular "Courier New" font (COUR.TTF). As a result, X clients
trying to set the font will hang, and killing the hung clients
brings down X.
The problem is that xfstt calls realloc(), through its #define
shrinkMem(), but neglects to adjust a pointer that used to
point to memory within the old block. A subsequent copying of
that pointer then merrily SIGSEGV's the code.
