Description:
------------
When the provided code get executed under Apache/mod_php, 
with APC enabled, only the FIRST request would result in 
warning:

======
Warning: The magic method __set() must have public 
visibility and cannot be static in test.php on line 5
======

When you request the file second time, no warning message 
appear - some how it was caught by APC and being omitted.

This Inconsistent behavior is hard to debug and wasted a lot 
of the development time. 
 



Reproduce code:
---------------
<?php

class Foo
{
     protected function __set($name, $value){}
     protected function __get($name) {}
}

echo "Loaded";

Expected result:
----------------
The warning message should always appear.


Actual result:
--------------
The warning message only appear in the 1st request.
