Description:
------------
When calling dns_get_record($host, DNS_AAAA) for a single specific hostname ("snowflake.nullroute.eu.org"), random garbage is appended to the 'ipv6' field of the DNS response.

The DNS response itself is valid (tested using Wireshark).

<tshark-output filter="udp port 53">
192.168.1.94 -> 8.8.8.8      DNS Standard query AAAA snowflake.nullroute.eu.org
     8.8.8.8 -> 192.168.1.94 DNS Standard query response AAAA 2001:470:1f0b:614:2ff:76ff:fe90:0
</tshark-output>

Copyright (c) 1997-2010 The PHP Group

Test script:
---------------
<?php
foreach (dns_get_record('snowflake.nullroute.eu.org', DNS_AAAA) as $r)
    var_dump($r['ipv6']);


Expected result:
----------------
string(33) "2001:470:1f0b:614:2ff:76ff:fe90::"

Actual result:
--------------
string(37) "2001:470:1f0b:614:2ff:76ff:fe90:XXXXX"

(where XXXXX is five random bytes)
