Description:
------------
If we throw exception from constructor and create object by "new" - destructor never called.

But if we create object by ReflectionClass - destructor always by called.

Test script:
---------------
<?php
class Test {
    public function __construct() {
        throw new Exception();
    }
    
    public function __destruct() {
        echo '__destruct';
    }
}

try {
    new Test();
} catch(Exception $e) {
    
}
echo '--';
try {
    $ref = new ReflectionClass('Test');
    $obj = $ref->newInstance();
} catch(Exception $e) {
    
}


Expected result:
----------------
--

Actual result:
--------------
--__destruct
