Description:
------------
If an implementation of Countable::count() does not return an 
int the result is a big, "random" number. It seems like the 
result is always taken as int even if it's a string or float.

IMHO the result should get typecasted to an int or at least a 
warning. If I typecast the result to an int in the return 
statement it works as expected. 

Reproduce code:
---------------
<?php

error_reporting(E_ALL | E_STRICT);

class Test implements Countable {
	function count() {
		return '1';
	}
}

$test = new Test();
var_dump(count($test));

?>

Expected result:
----------------
int(1)


Actual result:
--------------
int(148313044)
