Description:

Hi.

I have a script D:\PHP\Includes\auto_loader.php

My include_path=C:\PHP5\PEAR;D:\PHP\Includes;.

My auto_prepend_file=auto_loader.php

For this bug report, I've also set auto_append_file=show_includes.php

At the CLI, all is well.

Via CGI-FastCGI (I'm using IIS7, but I can replicate the issue via the 
commandline using php-cgi.exe), I get an extra entries.

Using ...
CD C:\
C:\PHP5\php.exe
C:\PHP5\php-cgi.exe

and pressing CTRL+Z (or F6) and then ENTER to leave PHP reveals the 
issue.

Interestingly, if I use ...

C:\PHP5\php-cgi -n -d 
auto_prepend_file=D:\PHP\Includes\auto_loader.php -d 
auto_append_file=D:\PHP\Includes\show_includes.php, then all is 
well.

So it seems reading the ini file and processing the 
auto_append_file/auto_prepend_file entries causes the issue. Maybe. It 
looks that way.

Reproduce code:
---------------
--------auto_loader.php
<?php
// Nothing needed here. All my code removed.
?>

-------show_includes.php
<?php
print_r(get_included_files());
?>

Expected result:
----------------
Array
(
    [0] => C:\-
    [1] => D:\PHP\Includes\auto_loader.php
    [2] => D:\PHP\Includes\show_includes.php
)

Array
(
    [0] => C:\-
    [1] => D:\PHP\Includes\auto_loader.php
    [2] => D:\PHP\Includes\show_includes.php
)

--------------

(
    [0] => C:\-
    [1] => D:\PHP\Includes\auto_loader.php
    [2] => D:\PHP\Includes\show_includes.php
