Dynamic_Predicate failure -> Assertion_Error?

[Jacob Sparre Andersen <jacob@jacob-sparre.dk>]

I am experimenting a bit with GNAT-GPL-2013 and some of the new features
in Ada 2012.

% cat primes.ads
package Primes is
   subtype Prime is Integer range 2 .. Integer'Last
     with Dynamic_Predicate
       => (for all N in 2 .. Prime - 1 => Prime mod N /= 0);
end Primes;
% cat test_primes.adb
with Ada.Assertions,
     Ada.Text_IO;
with Primes;

procedure Test_Primes is
   use Primes;
   P : Prime;
begin
   for I in 1 .. 25 loop
      begin
         P := I;
         Ada.Text_IO.Put_Line (Prime'Image (P) & " is a prime.");
      exception
         when Constraint_Error =>
            Ada.Text_IO.Put_Line (Integer'Image (I) &
                                  " is not a prime (constraint).");
         when Ada.Assertions.Assertion_Error =>
            Ada.Text_IO.Put_Line (Integer'Image (I) &
                                  " is not a prime (predicate).");
      end;
   end loop;
end Test_Primes;
% gnatmake -gnat12 -gnata -gnato -fstack-check test_primes
gcc -c -gnat12 -gnata -gnato -fstack-check test_primes.adb
gcc -c -gnat12 -gnata -gnato -fstack-check primes.ads
gnatbind -x test_primes.ali
gnatlink test_primes.ali -fstack-check
% ./test_primes
 1 is not a prime (constraint).
 2 is a prime.
 3 is a prime.
 4 is not a prime (constraint).
[...]

As I read 3.2.4(31/3) the raised exception for 4 should be
Assertion_Error and not Constraint_Error.  Is this correct?

If I am correct, is there any likelihood that I could get a test for
this into ACATS (assuming that I can figure out how to formulate it
properly)?

Greetings,

Jacob
