Description:
------------
The following works as expected (with the first parameter of test() accepting a reference) and doesn't throw a notice:

test($foo = 2 /* anything not being an object */);

But objects omit that notice. Seems to be a PHP 4 relict, but today this should definitely emit a notice.

Test script:
---------------
test($foo = new stdClass);

function test(&$param) {
        $param = 1;
}

var_dump($foo);

Expected result:
----------------
Notice: Only variables should be passed by reference in - on line 5
object(stdClass)#1 (0) {
}


Actual result:
--------------
object(stdClass)#1 (0) {
}
