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.

Please do not submit the same bug more than once. An existing
bug report already describes this very problem. Even if you feel
that your issue is somewhat different, the resolution is likely
to be the same. 

Thank you for your interest in PHP.

Note to self: "submitted twice" isn't very useful. Sorry about the bugspam.

Duplicate of bug #64917, anyway.
