Bug description:  $_POST not filled, altough raw POST is available

Description:
------------
Maybe this bug is related to Bugs 31417 and 41293.  But I'm not sure,
because this bug occurs in 5.2.0 and 5.2.2.


The problem is: 

When sending POST requests via the XmlHttpRequest active-x, on some IE6
installations this won't work properly. The POST request is successfully
sent to our webserver,  and the raw http post data is filled correctly, but
the $_POST array is not  filled with any information.

I can only guess that the error has something to do with some special
headers/encoding (Content-Length?) which is done by the
XmlHttpRequest-ActiveX on some IE6 installations.

And: Yes, I know that it's hard to find the reason for this behaviour. And
it's not easy to reproduce this bug ( because on most IE6 installations
everything works fine). 

But I guess it's worth to take a look at the php-source, so that someone
may get an idea which could cause this bug. 

I'm trying to help you as much as possible. Unfortunately I cannot
reproduce the error by myself, so I have to ask the affected customers 
each time we 'possibly' fixed the bug. 

There must be a bug in php, because the raw-http request is filled
correctly (and we don't touch the $_POST var anywhere else in our code).

Reproduce code:
---------------
var_export($_POST);
$rawPost = file_get_contents('php://input');
echo "\n$rawPost";


Expected result:
----------------
array('postVar1' => 'postValue1',
'postVar2' => 'postValue2')

postVar1=postValue1&postVar2=postValue2

Actual result:
--------------
array()

postVar1=postValue1&postVar2=postValue2
