Symbol discovery does not find functions returning references #3829

The function get_smarty is in another file and looks like this:
function &get_smarty ()
{
global $smarty;
return $smarty;
}
The discovery of other functions and symbols works fine, and if I remove the & the error goes away so I think the symbol discovery has a bug related to function returning by reference.
