Description:
------------
When I use SimpleXML to find some element's attributes, A mistake leads to 
infinite loop.

I was meaning "$child->atttibutes()", but "$childs->attributes()" by mistake, 
then some strange things happen: Infinite loop.

Is it a bug?

Test script:
---------------
<?php
$xml = simplexml_load_string('<root><parent><child id="1"/><child id="2"/></parent></root>');
$childs = $xml->parent->child;
foreach($childs as $child){
	var_dump($childs->attributes());
}
?>

Expected result:
----------------
Print:

object(SimpleXMLElement)#6 (1) {
  ["@attributes"]=>
  array(1) {
    ["id"]=>
    string(1) "1"
  }
}
object(SimpleXMLElement)#6 (1) {
  ["@attributes"]=>
  array(1) {
    ["id"]=>
    string(1) "1"
  }
}

Actual result:
--------------
Infinite loop.
