Thank you for this bug report. To properly diagnose the problem, we
need a short but complete example script to be able to reproduce
this bug ourselves.
A proper reproducing script starts with <?php and ends with ?>,
is max. 10-20 lines long and does not require any external
resources such as databases, etc. If the script requires a
database to demonstrate the issue, please make sure it creates
all necessary tables, stored procedures etc.
Please avoid embedding huge scripts into the report.

Same results in 5.2.9 as with 5.2.12.

It works with other array values, if you replace
$list[] = $node->attributes();
with
$c = array();
$list[] = $c;
it resets the iteration at the same node.
$list[] = array();
does not reset the iteration however.
$list[] = new stdClass();
does reset the iteration.
Adding simple integers or strings to the array do not reset.

Description:
------------
When iterating over a large xml object and storing attributes of all
nodes in an array, somehow the iteration gets reset (always at the same
element)
Tested with 5.3.1 and php-5.3 svn HEAD, does not occur on php-5.2.12.
Reproduce code:
---------------
<?php
function traverse($node)
{
static $list;
foreach ($node->children() as $child) traverse($child);
$list[] = $node->attributes();
echo $node['id'] . "\n";
}
traverse(new SimpleXMLElement('data.xml', null, true));
data.xml:
<?xml version="1.0"?>
<rowset>
<row id="1" />
[...]
<row id="14999" />
</rowset>
Expected result:
----------------
1
2
3
[.. continuous numbers ..]
14997
14998
14999
Actual result:
--------------
1
2
3
[.. continuous numbers ..]9994
9995
9996
2
3
4
[.. continuous numbers ..]
