Description:
------------
Ok, Pierre was writing this is a separate issue then #54197. So I'm opening a new one. 

The crash happens with PHP CGI if you are setting user_ini.filename at global level to none. And you must also have a PATH section for the current script.

This only happens with Windows. With *nix it's working as expected.

Test script:
---------------
adding this to "php.ini":
user_ini.filename =
[PATH=C:/Users/Public/Documents/htdocs/]
upload_max_filesize = 5M

And then accessing a phpinfo.php through CGI.
<?php
phpinfo();
?>


Expected result:
----------------
user_ini.filename	no value	no value
upload_max_filesize	5M		2M


Actual result:
--------------
php-cgi is crashing.
