requeue with abort and timed call

[ishikawa@arielworks.com]

Hi,

I found a strange behavior of GNAT about requeue-with-abort.

In the RM,  I found the following definition
>16  * if the original entry call was timed (or conditional), then the original expiration time is the expiration time for the requeued call.
(http://www.adaic.org/standards/1zrm/html/RM-9-5-4.html)

But In the following code,  its timed entry call had never be aborted.
When "Original_Call" does not have "delay 3.0", it got aborted.

It seems that "Original_Call" takes more than 1.0 second(over the
expiration time of the timed call), "with abort" does not work as
intended.
I think the requeued call should be aborted in this case.

Does anyone understand whether this behavior is a bug or not?
I could not find any definition supporting this behavior on RM.

------
with Ada.Text_IO; use Ada.Text_IO;
procedure Req is
   task T is
      entry Original_Call;
      entry Requeued_Call;
   end T;

   task body T is
   begin
      loop
      accept Original_Call do
         Put_Line ("Original Call...");
         -- takes three seconds
         delay 3.0;
         Put_Line ("Original Call Done");
         requeue Requeued_Call with abort;
      end Original_Call;

      -- inifinity loop
      loop
         delay 10.0;
      end loop;

      -- will be never accepted
      accept Requeued_Call do
         Put_Line ("Requeued_Call");
      end Requeued_Call;
      end loop;
   end T;

begin
   select
      T.Original_Call;
   or
      -- just wait 1 second
      delay 1.0;
      Put_Line ("Aborting");
   end select;
   Put_Line ("Parent Done");
end Req;
