Bug description:Implicit call to spl_autoload_call() does not throw exceptions

Description:
------------
Exceptions thrown from custom autoload function are not thrown outside the

spl_autoload_call() function when it is implicitly called on expressions
like 
'A::someMethod();' and '$b = A::CONSTANT;', i.e. when accessing static
methods 
and constants of the class.

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

function autoload($class)
{
    debug_print_backtrace();
    throw new Exception('Test message');
}

spl_autoload_register('autoload');

try {
    A::$someVariable;
} catch (Exception $e) {
    echo $e->getMessage() . "\n";
}

try {
    A::someMethod();
} catch (Exception $e) {
    echo $e->getMessage() . "\n";
}

Expected result:
----------------
#0  autoload(A)
#1  spl_autoload_call(A) called at [/tmp/1.php:12]
Test message
#0  autoload(A)
#1  spl_autoload_call(A) called at [/tmp/1.php:18]
Test message

Actual result:
--------------
#0  autoload(A)
#1  spl_autoload_call(A) called at [/tmp/1.php:12]
Test message
#0  autoload(A)
#1  spl_autoload_call(A) called at [/tmp/1.php:18]
PHP Fatal error:  Class 'A' not found in /tmp/1.php on line 18
PHP Stack trace:
PHP   1. {main}() /tmp/1.php:0
