Does Free Pascal work the same as Delphi 7 and earlier when you pass
interfaces around (and perhaps other auto reference counted types -
strings, dynamic arrays?). Without a classifier (const, var, out), an
interface argument reference count gets inc'd on the way in to the
function and dec'd on way out, resulting in calls to _AddRef and
_Release respectively on the interfaced argument.
