Description:
------------
putting an empty array onto a COM object leads to severe reactions from
the system. Memory usage escalates dramatically (my system showed
1.6G), the machine slows to a crawl even though system idle does not
reflect it, and it has crashed FF, too, when I had many windows open.
Running this from CLI php.exe produces a noticable delay, but the
really severe reaction comes when running it as a web page.

Reproduce code:
---------------
<?php
$dict = new COM("Scripting.Dictionary");
$dict->add('foo', array());
print sizeof($dict['foo']); // bug: large #
$dict->add('bar', array(23));
print " " . sizeof($dict['bar']) . " \n"; // OK: 1
$ie = new COM("InternetExplorer.Application");
$ie->navigate("about:blank"); // to get a document object
$window=$ie->document->parentWindow;
$window->execScript("window.myArray=false"); //placeholder
$window->myArray = array();
print sizeof($window->myArray); // bug: large #
$window->myArray = array(23);
print " " . sizeof($window->myArray); // OK: 1
?>
Expected result:
----------------
On the output for the empty arrays, I should get 0 and not some number
in the millions. But especially, running the code above should not
lock up the system.
The last two statements of each of the two code sections are showing
correct behaviour and are not part of the bug.
