I have the same problem on my machine and can confirm this bug!
i think this bug affects mod_spdy aswell, because it sends the POST data chunked!

Description:
------------
When a POST is sent with the header "Transfer-Encoding: chunked" and PHP 5.3 is 
running via FastCGI, $HTTP_RAW_POST_DATA is not set. In IIS, the receiving PHP 
process simply hangs and does not execute at all. If chunked encoding is not set, 
it executes successfully and $HTTP_RAW_POST_DATA is populated.

Comparing ISAPI to FastCGI (using PHP 5.2 which has both implementations), PHP 
ISAPI works fine with "Transfer-Encoding: chunked" but PHP FastCGI does not.

This issue also occurred running Linux/Apache with PHP 5.3 FastCGI. In that 
scenario, the PHP process did not completely hang, but $HTTP_RAW_POST_DATA and 
php://input were empty when the script executed.

Test script:
---------------
Two files, postsend.php and postreceive.php, can be found within the question here:

http://stackoverflow.com/questions/8899239/http-raw-post-data-not-being-populated-after-upgrade-to-php-5-3

Expected result:
----------------
$HTTP_RAW_POST_DATA and the php://input stream should contain the raw binary data 
that was sent in the POST.

Actual result:
--------------
On Windows/IIS, the PHP process hangs and does not execute.
On Linux/Apache, the PHP process executes but $HTTP_RAW_POST_DATA and php://input 
are empty.
