Description:
------------
After upgrading from PHP 5.6.27 to 7.1.0RC6 dns_get_record stopped returning additional records in its out parameter. I've confirmed with tcpdump that PHP (libresolv I imagine) sends the same request as before, and gets the same answer (with additional records), yet $additional array in the following code is no longer populated.

Test script:
---------------
The actual code I'm trying to get working is:
<?php
$auth = [];
$additional = [];

var_dump(dns_get_record("_mysql._slave.service.consul", DNS_SRV, $auth, $additional), $auth, $additional);
?>

However it depends on consul service discovery. 

Simpler reproduce script would be:
<?php
$auth = [];
$additional = [];

var_dump(count(dns_get_record("php.net", DNS_ANY, $auth, $additional)), count($auth), count($additional));
?>

Yet it requires known DNS server that returns additional records to be configured as your preferred recursor in /etc/resolv.conf (I used PHP.net's authoritative DNS server below):
nameserver 162.159.24.53

Expected result:
----------------
With php.net script above, with resolv.conf configured as described there, running on PHP 5.6.27 I get:

int(9)
int(0)
int(8) <--- $additional is NOT empty


Actual result:
--------------
Running on PHP 7.1.RC6 (otherwise configured the same) I get:

int(9)
int(0)
int(0) <--- $additional IS empty
