gnat 3.15p with kernel 2.6 / SuSE 9.1

[my_spam@bluewin.ch (Thomas Aho)]

I have a problem with gnat 3.14p hanging on a SuSE 9.1 system (kernel
2.6). As soon as there are tasks involved, the program hangs, as soon
as the task is being activated. An example:

with Text_Io;

procedure Amain is

   task type Tt is
      entry Start;
      entry Stop;
   end;

task body Tt is
   Exit_Flag : Boolean := False;
begin
   accept Start;
   while not Exit_Flag Loop
      Text_Io.Put_Line("hello");
      select
         accept Stop;
         Exit_Flag := True;
      or delay 1.0;
      end select;
   end loop;
end;

begin
   Text_Io.Put_Line("start");
   declare
      T1 : Tt;
      begin
         t1.Start;
         delay 5.0;
         T1.Stop;
      end;
end Amain;


This program will only report "start", and then nothing more.

I have made sure that the gcc that is found is 2.8.1 (which is the
backend for gnat 3.15), so there is no gcc2-gcc3 conflict.
Does anyone have experinced similar problems?
