<?
class test {
var $num;

function test($p) {
	$this->num=$p;
}

function nothing() {}

}

$temp[0]=new test("foo");
echo htmlentities(serialize($temp));
$temp[0]->nothing();
echo "<p>".htmlentities(serialize($temp));
?>

The above script gives me the following output:

----
a:1:{i:0;O:4:"test":1:{s:3:"num";s:3:"foo";}}
a:1:{}

This too breaks the session functions for that object.
