Based on the notice you get and on an answer to another related question:

In PHP assignment expressions always return the assigned value. So $_config[0] =& $config returns $config - but not the variable itself, but a copy of its value. And returning a reference to a temporary value wouldn't be particularly useful (changing it wouldn't do anything).

Changing your code from:

return new BEncode_End();

To:

$cl = new BEncode_End();
return $cl;

Should solve your problem.
