--- Comment #6 from baptiste fouques <bat at m4tp dot org> 2011-10-06 10:58:56 UTC ---
seems still present in gcc 4.5.3

it passes OK in most situations, but fails with 2005 extension and match
checks.

should be re-opened

---

generic
   type Data is range <>; -- would pass with "Type Data is private" or anything
even less constraint
   type Table is array (Positive range <>) of access Data;
package Test is

end Test;

---

with Test;

package Test_2 is

   type My_Data is range 0 .. 16#ff#;
   type Data_Table is array (Positive range <>) of access My_Data;

   package Instance is new Test
     (
      Data  => My_Data,
      Table => Data_Table
     );

end Test_2;

---

gcc -c -gnatc -g -gnatq -gnatQ test_2.ads
test_2.ads:11:16: component subtype of actual does not match that of formal
"Table"
test_2.ads:11:16: instantiation abandoned
