I was trying the following elisp, and ended up with an unexpected result...

(setq udp-cl
      (make-network-process
       :name "baz" :buffer nil
       :service 53 :host "64.68.192.10"
       :family 'ipv4 :filter (lambda (p s)
			       (print s))
       :type 'datagram
       :coding 'binary))

(process-datagram-address udp-cl)
 => [64 68 192 10 53]
(set-process-datagram-address udp-cl (process-datagram-address udp-cl))
 => [64 68 192 10 53]
(process-datagram-address udp-cl)
 => [0 0 0 0 53]

Can anybody else duplicate this?
