Description:
------------
PHP 5 beta 2 seems to do strange things when using a comaprisson wiht negative values in an If-clause. Sometimes the if-part will work as well as the else-part and sometimes the if-part will be used two times.

Reproduce code:
---------------
$x = -1;
if($x == -1){ echo "if"; } else { echo "else"; }

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

Actual result:
--------------
ifif

Works fine for me...:

derick@kossu:~$ php-5.0dev
<?php $x = -1;
if($x == -1){ echo "if"; } else { echo "else"; }
?>
if

This Code was used in a class. I didn't notice that the problem seems to be connected with that fact.

Please provide a COMPLETE (as short as possible) source code that can be used to replicate the problem.

class categories {
	
	function getfolders($folderid = -1, $depth = -1) {
		
		if($folderid == -1) {
			echo "if";
		} else {
			echo "else";
                }
        }
}

$categories = new categories

$categories->getfolders(6);



the output is "ifelse" in my case.

Once the parse error in the sample script is fixed it works perfectly.
