"raise" and stack trace

Question

Greetings,
When re-raising an exception, the error stack is lost.
I am using Oracle Database 10g Release 10.1.0.4.0 - 64bit Production on Red Hat Enterprise Linux ES release 4 (Nahant Update 1)
Consider the following code:
SQL> declare
  2    L_DUMMY  char(1);
  3  --
  4    procedure P
  5    is
  6    begin
  7      select 'X' into L_DUMMY from DUAL where 1 = 0;
  8    end;
  9  begin
10    P;
11* end;
12  /
declare
ERROR at line 1:
ORA-01403: no data found
ORA-06512: at line 7
ORA-06512: at line 10When I add an exception handler to above code and use "raise" to re-raise the exception, the stack trace is lost, as shown below:
SQL> declare
  2    L_DUMMY  char(1);
  3  --
  4    procedure P
  5    is
  6    begin
  7      select 'X' into L_DUMMY from DUAL where 1 = 0;
  8    end P;
  9  begin
10    P;
11  exception
12    when others then
13      raise;
14  end;
15  /
declare
ERROR at line 1:
ORA-01403: no data found
ORA-06512: at line 13Is there some way to keep the stack trace when re-raising an error?
Thanks,
Avi.

What about using raise_application_error used with TRUE as third parameter?

   l_dummy   char (1);
   procedure p
   is
   begin
      select 'X' into l_dummy from dual where 1 = 0;
   exception
      when others
      then
         raise_application_error (-20000, sqlerrm (sqlcode), true);
   end p;
begin
   p;
exception
   when others
   then
      raise_application_error (-20000, sqlerrm (sqlcode), true);
end;

ORA-01403: no data foundEventhough I still see no real use in here ...
