Description:
------------
The PHP shutdown process does not seem to complete when PHP is passed a filename. Instead the function clean_non_persistent_constants appears to abort the process on this line: http://lxr.php.net/xref/PHP_5_6/Zend/zend_constants.c#142

I found this by trying to enable the Garbage Collector benchmark as described on:
http://php.net/manual/en/features.gc.performance-considerations.php


After recompiling PHP with `export CFLAGS=-DGC_BENCH=1` I expect to see GC benchmarks after every php script is run. Instead only scripts that are piped in to PHP give benchmarks.

i.e. 

Running `php < memTest.php` - this appears to exit properly and shows the GC benchmarks


Running `php memTest.php` - this appears to exit prematurely in the clean_non_persistent_constants function.

To be honest, it may have been like this for such a long time that fixing this is a bad idea...and that just moving the GC benchmark output to above where it exits early would be more appropriate.


Test script:
---------------
<?php

echo "Hello world!";

Expected result:
----------------
GC Benchmark output after every script is run.

Actual result:
--------------
GC Benchmark output only after scripts are piped into PHP, rather than php running file names.
