gnatmake -g foo.adb -bargs -E for the following modified code. You will be pleasantly surprised that addr2line is not needed explicitly.

with Gnat.Traceback.Symbolic;
with Ada.Exceptions; use Ada;
with Ada.Text_IO; use Ada.Text_IO;

procedure Foo is 

   procedure Able is 
   begin 
      raise Constraint_Error with "It broke"; 
   end Able; 

   procedure Baker is 
   begin 
      Able; 
   end Baker;

begin 
   Baker; 
exception
   when Err : others =>
      Put_Line ("Houston we have a problem: " &
                                       Exceptions.Exception_Information(Err));
      Put_Line (GNAT.Traceback.Symbolic.Symbolic_Traceback(Err));
end Foo;
