That's really strange.  The relevant client.c code is:

    /* setup address_list */
    if(c->opt->option.delayed_lookup) {
        resolved_list.num=0;
        if(!name2addrlist(&resolved_list,
                c->opt->remote_address, DEFAULT_LOOPBACK)){
            s_log(LOG_ERR, "No host resolved");
            longjmp(c->err, 1);
        }
        address_list=&resolved_list;
    } else /* use pre-resolved addresses */
        address_list=&c->opt->remote_addr;

Maybe you use some kind of advanced/broken resolver library that caches IP
addresses?
