Description:
------------
I just upgraded to PHP 5.4 and figured I'd test the built-in web server. It runs fine, 
but 
always crashes when it's closing. I have APC enabled in my php.ini and according to the 
backtrace that is the problem. Removing APC from php.ini fixes it.

Regardless of whether the program starts successfully or not (arbitrary invalid 
arguments 
produce the same result), it will always crash on shutdown.

I am using PHP 5.4.0 and APC-3.1.9. I haven't had any problems with APC using CGI.

Test script:
---------------
$ php -S ?

Expected result:
----------------
An error message and clean exit.

Actual result:
--------------
(gdb) run -S ?
Starting program: /usr/local/bin/php -S ?
[Thread debugging using libthread_db enabled]
