GCC 11.1.0, x86_64-apple-darwin on macOS 11.6 (Big Sur):
This compiles without error, and the example below executes correctly.
with P;
with Ada.Text_IO;
procedure P_Test is
package Q is new P;
R : aliased Q.R := (Item => 42);
T : Q.T := Q.F (R'Access);
begin
Ada.Text_IO.Put_Line (T.D.all'Image);
end P_Test;
