Description:
------------
When exceptions are thrown in destructor, PHP5.3.x does not catch any exceptions 
in caller's "try" block.
In addition, destructor's "try" block catches exceptions of caller.

Probably this behavior is bug because it works correctly on PHP5.2.13.

Test script:
---------------
<?php
class aaa {
	public function __destruct() {
		try {
			throw new Exception(__CLASS__);
		} catch(Exception $ex) {
		}
	}
}
function bbb() {
	$a = new aaa();
	throw new Exception(__FUNCTION__);
}
try {
	bbb();
	echo "must be skipped !!!";
} catch(Exception $ex) {
	echo $ex;
}

Expected result:
----------------
exception 'Exception' with message 'aaa' in example.php:5
Stack trace:
#0 example.php(16): aaa->__destruct()
#1 example.php(16): bbb()
#2 {main}
exception 'Exception' with message 'bbb' in example.php:13
Stack trace:
#0 example.php(16): bbb()
#1 {main}

Actual result:
--------------
exception 'Exception' with message 'bbb' in example.php:13
Stack trace:
#0 example.php(16): bbb()
#1 {main}

Next exception 'Exception' with message 'aaa' in example.php:5
Stack trace:
#0 example.php(16): aaa->__destruct()
#1 example.php(16): bbb()
#2 {main}
must be skipped !!!
