 subject: krb5_walk_realm_tree leaks in capaths case
 target_version: 1.6.2
 tags: pullup
 
 Markus Moeller reports a leak in krb5_get_credentials() which was then
 traced down to profile strings leaking from within
 krb5_walk_realm_tree().  A pointer to a profile string was getting
 overwritten without the string being freed when *cap_nodes[0] == '.'.
 Fix is to free the string prior to overwriting the pointer if the
 pointer is non-null.
