Description:
------------
If a user definded error handler is present the autoloader registered with spl_register_autoloader isn`t called in certain cases. This bug was not present in PHP 5.3 but can be reproduced in all Versions of 5.4 and 5.5

Test script:
---------------
https://docs.google.com/file/d/0ByiEkxk4BDg0cUE2ZzRuaXNRSjA/edit

Expected result:
----------------
To reproduce the bug please extract the ZIP file from the provided URL and run test.php. The autoloader is expected to require the other files (a.php, b.php, c.php) as needed.

Actual result:
--------------
"Fatal error: Class 'c' not found" occurs. If the custom error handler is removed the autoloader works as expected.

Verified that this is a problem in PHP 5.4.24 on Mac OS X 10.9.3.

A quick investigation shows that the body of this if branch is taken when looking up 'c': http://lxr.php.net/xref/PHP_TRUNK/Zend/zend_execute_API.c#949

949    /* The compiler is not-reentrant. Make sure we __autoload() only during run-time
950     * (doesn't impact functionality of __autoload()
951    */
952    if (!use_autoload || zend_is_compiling(TSRMLS_C)) {
953        if (!key) {
954            free_alloca(lc_free, use_heap);
955        }
956        return FAILURE;
957    }

use_autoload is set to 1, so it must be the zend_is_compiling call.
