Function: ldap_domain2hostlist line 266ff:

	buflen = strlen(host) + sizeof(":65355");                                  
	hostlist = (char *) LDAP_REALLOC(hostlist, cur + buflen);
	if (hostlist == NULL) {
	    rc = LDAP_NO_MEMORY;
	    goto out;
	}
	if (cur > 0) {
	    /* not first time around */
	    hostlist[cur++] = ' ';
There might not be enough space in hostlist for the ' '
	}
	cur += sprintf(&hostlist[cur], "%s:%hd", host, port);

This issue however seems to be fixed in HEAD. Will it be backported to
OPENLDAP_REL_ENG_2 ?
