liblber/debug.c:lutil_log_int() does
	t_subsys = strdup(subsys);
but never frees t_subsys.
However, this code is broken anyway.  First, it strdup()s the value even
in cases it is not needed (when the function return;s without using it).
Second, why strdup it at all?  I suggest you print the subsystem in its
original case, or uppercase it in lutil_subsys[], or uppercase it in
a lutil_subsys_uppercase[] array which contains an uppercased copy of
lutil_subsys[].
