[Bug ada/34508] New: Legal program rejected, RM 3.7(26)

package pak1 is
   type T1(<>) is tagged limited private;
private
   type T1(D: integer) is tagged limited null record;
end pak1;

package pak1.pak3 is
   type T3 is new pak1.T1 with null record;   -- legal, but rejected
   x2: T3 := (pak1.T1 with null record);      -- legal, but rejected
end pak1.pak3;

RM 3.7(26) states: "A type declared without a discriminant part has no
discriminants, unless it is a derived type; if derived, such a type has the
same sort of discriminants (known, unknown, or none) as its parent (or
ancestor) type."  Therefore, the declaration of T3 is legal and T3 has unknown
discriminants.
