I submitted a GNAT bug report yesterday.

It seems, that GNAT does not handle derived types in combination with
generic units correctly.

Another example:

with Unchecked_Deallocation;
package String_Utils; is
   type String_Access is access String;
   procedure Free is new Unchecked_Deallocation (String, String_Access);
end String_Utils;

with String_Utils;
procedure Main is
  type Derived_From_String_Access is new String_Utils.String_Access;
  X : Derived_From_String_Access;
begin
  Free(X);
end Main;
main.adb:6:03: expected type "String_Access" defined at string_utils.ads:3
main.adb:6:03: found type "Derived_From_String_Access" defined at line 3
main.adb:6:03: expected type "Derived_From_String_Access" defined at line 3
main.adb:6:03: found type "String_Access" defined at string_utils.ads:3

It is a little surprising that nobody has found this bug in the past.
