Description:
------------
When performing an operation which throws an exception in the __destruct method of a class, the following Error is generated

Fatal error: Exception thrown without a stack frame in Unknown on line 0

I have only observed this happening when an object goes out of scope because the script has ended. Rather than generating a scripting engine error, PHP should allow for the script to deal with the error, for instance when an exception handler has been specified by the script.

Reproduce code:
---------------
    class test {
        function __construct() {
            echo "Construct\n";
        }
        
        function greet() {
            echo "Hello World\n";
        }
        
        function __destruct() {
            echo "Destruct\n";
            throw new Exception( 'test' );
        }
    }
    
    $test = new test();
    $test->greet();

Expected result:
----------------
Construct
Hello World
Destruct

Fatal error: Uncaught exception 'Exception' with message 'test' in /home/crazzeto/test.php:13
Stack trace:
#0 /home/crazzeto/test.php(13): test::__destruct()
#1 /home/crazzeto/test.php(20): test::__destruct()
#2 /home/crazzeto/test.php(20): unknown()
#3 {main}
  thrown in /home/crazzeto/test.php on line 13


Actual result:
--------------
[crazzeto@DEVEL crazzeto]$ php test.php
Construct
Hello World
Destruct

Fatal error: Exception thrown without a stack frame in Unknown on line 0
