Description:
------------
When updating PHP5 to the latest version (5.2.5-2 or newer), using the LDAP extension produces a crash, causing the script to abort.

Version 5.2.4-2 was latest version, that didn't crash that way. Also tried with 5.2.5-2, but same problem.

Reproduce code:
---------------
function get_ldap_name($unix)
{
	$ds = ldap_connect("ldap.example.com");
	$ldap_arr = get_ldap_info($unix, $ds);
	if ((is_array($ldap_arr)) && array_key_exists(0, $ldap_arr)) {
		$data = $ldap_arr[0]['cn'][0];
		ldap_close($ds);
		return $data;
	}
	ldap_close($ds);
	return false;
}


Expected result:
----------------
Script returns the full name of the user specified

Actual result:
--------------
tail -f /var/log/apache2/error.log
