------- Additional Comments From laurent at guerby dot net  2005-06-19 11:46 -------
Here is a reduced test case, works at -0O, fails at -O1 works at -O1
-fno-tree-dce. First .tNN to be different is p.adb.t24.forwprop1.

procedure P is
   function F return Integer is
   begin
      return 1;
   end F;
   A : array (-F .. 1) of Boolean;
begin
   A := (False,True,False);
   A(-1 .. 0)  :=  A (0 .. 1);
   if A /= (True, False, False) then
      raise Program_Error;
   end if;
end P;
