Description:
------------
If I use __autoload() PHP says "__autoload threw an exception" while I throw an exception which would be caught somewhere between several catch statements.

That means __autoload() first loads the Class for the thrown Exception then PHP searches a catch statement for the threwn  exception. The first statement is for another Exception (the exception still is uncaught) so __autoload should load this class. But here it fails and says "__autoload threw an exception".

A Workaround would be to require all Exceptions for all catch Statements before any exception is thrown.

Reproduce code:
---------------
// Be sure that Test1.php and Test2.php exists

function __autoload($className) {
    echo '<br>' . $className;
    require_once ucfirst($className) . '.php';
    echo 'loaded';
}

// If I would do "require_once Test1.php;" here
// everything would work

try {

    throw new Test2();

} catch(Test1 $e) {

} catch(Test2 $e) {

}

Expected result:
----------------
test2loaded
test1loaded

Actual result:
--------------
test2loaded
test1
