Memory leak

[Russell Shaw]

Hi,
In my code, i have:

    malloc_stats();

    Xutf8DrawString(
         app->display,
         win,
         wm->fontset.fontset,
         wm->title_gc.gc,
         x,
         y,
         cli->title,
         strlen(cli->title)
    );

    malloc_stats();


malloc_stats() shows a leak of 56 bytes:

Arena 0:
system bytes     =    2834432
in use bytes     =    2540544
Total (incl. mmap):
system bytes     =    2834432
in use bytes     =    2540544
max mmap regions =          0
max mmap bytes   =          0

(gdb) next
...

Arena 0:
system bytes     =    2834432
in use bytes     =    2540600
Total (incl. mmap):
system bytes     =    2834432
in use bytes     =    2540600
max mmap regions =          0
max mmap bytes   =          0


By using a malloc hook, it seems the pointer to the memory from
Xutf8DrawString() is not freed.
