Description:
------------
First, I don't think this is PHP 5.3 RC related or Linux related, but at the moment I have no chace to check on XP with 5.2.
Neither did I know which category it should be in.
Please check this, thanks.

It took a while to find this. The real problem is shown in the reproduce code section.

This code works, it calls x() which will throw an Exception and output "ERROR"

<?php
try {
	function x() { throw new Exception("ERROR"); }
	(x());
} catch(Exception $e) {
	echo($e -> getMessage());
}
?>


Reproduce code:
---------------
<?php
try {
	function x() { throw new Exception("ERROR"); }
	x(x());
} catch(Exception $e) {
	echo($e -> getMessage());
}
?>

Expected result:
----------------
Expected would that the inner x() will throw the Exception, the outer one would be skipped and I get the "ERROR" string from the Exception in the catch

Actual result:
--------------
a blank page.
