I think GNAT GPL 2009 might just have a problem in this area: this is
accepted
procedure Q is
X : P.T'Class := P.S'(P.Value);
begin
X := P.T'(P.Value);
but this fails
procedure Q is
X : P.T'Class := P.T'(P.Value);
begin
X := P.S'(P.Value);
saying 'tag-indeterminate expression must have type "T"(RM 5.2 (6))'
