Description:
------------
PHP segfaults when trying to resolve a hostname internally. We encountered this with mysql_connect, gethostbyname, socket_connect in:
- PHP 5.0.5 (cgi-fcgi AND cli)
- PHP 4.4.0
All when run from shell.

Reproduce code:
---------------
<?php
echo gethostbyname("www.google.com");
?>

Expected result:
----------------
64.233.183.99

Actual result:
--------------
Segmentation fault (core dumped)
