Bug description: endless loop with children() iterator

Description:
------------
Not sure if this a bug or a feature, but when applying a fixed reference
to a member of the iterator returned by the children() method in a foreach
construct, it gets stuck in an infinite loop.

Reproduce code:
---------------
<?php

$xml = '<parent><element /><child /></parent>';
$xmldoc = simplexml_load_string($xml);
$elements = $xmldoc->children();

foreach ($elements as $element) {
$elements[0];
}

?>

Expected result:
----------------
Finished after a couple of seconds at most.

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

New Comment:

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the do***entation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php

You are using the same iterator twice. Thus the loop body resets
itself.
