Description:
------------
   Trying to upload files which exceed the post_max_size param from php.ini fails without any errors transmitted to the PHP script that handles the upload. This is the logged error.
   [error] PHP Warning:  POST Content-Length of 11184886 bytes exceeds the limit of 8388608 bytes in Unknown on line 0
    I did specify MAX_FILE_SIZE in the HTML form, before the
<Input type=file ... block.
    The engine discards the download and gives no error.
The $_FILES and any other server vars are completely empty; no error about the broken upload.

php.ini:
memory_limit = 48M 
post_max_size = 8M 
file_uploads = On 
upload_max_filesize = 8M 
allow_url_fopen = On 


Reproduce code:
---------------
<FORM name='up' enctype='multipart/form-data' method='POST' action='<?php echo $PHP_SELF ?>'>
<INPUT type='hidden' name='MAX_FILE_SIZE' value='5242880' />
<INPUT type='file' name='up_file' size='50' />
<INPUT type='submit' name='submit' />
</FORM>

<?php
  if(!empty($submit)) {
    print_r($_FILES);
    phpinfo();
  }
?>

Expected result:
----------------
   Since I tryied to upload a file which exceeds both the MAX_FILE_SIZE and the post_max_size I would have expected to find some sort of error in the $_FILES['up_file']['error'] or anywhere else in the PHP variables, but
I found no such error(s).

Actual result:
--------------
    No result whatsoever except the log:
[error] PHP Warning:  POST Content-Length of 11184886 bytes exceeds the limit of 8388608 bytes in Unknown on line 0
