Description:
------------
PHP version is 5.3.6

When setting the apc.stat=0.
There is hello.php, when I　modify the output of 
hello.php.
The output page doesn't change. 
That means apc.stat=0 works on such condition.
But when I rename hello.php as h.php.
The error shows:
No input file specified.

I am checking the "sapi/fpm/fpm/fpm_main.c" line 1903.
That means, when working with fpm, PHP will check each time 
for the file exist. Cause apc.stat=0 not work.



Reproduce code:
---------------
<?PHP
echo 'Hello world!'



Expected result:
----------------
When rename the hello.php as h.php.
Output will be Hello world!

Actual result:
--------------
No input file specified.
