How to get the entire trace with dbms_utility.format_error_backtrace

Question

Hi,
I made 35 procedures where test35 is
calling test34 and test34 is calling test33 etc.
division-by-zero is in test1 and format_error_backtrace shows the trace up to test31.
Just curious, is it possible to get the entire trace?
Thanks
An example
SQL> BEGIN
  2  EXECUTE IMMEDIATE 'create or replace procedure test1 as a number; begin a:=1/0; end;';
  3  FOR i IN 2..35 LOOP
  4   execute immediate 'create or replace procedure test'||i||' as begin test'||(i-1)||'; end;';
  5  END LOOP;
  6  END;
  7  /
PL/SQL procedure successfully completed.
SQL> BEGIN
  2    test35;
  3  EXCEPTION WHEN OTHERS THEN
  4   dbms_output.put_line(dbms_utility.format_error_backtrace);
  5  END;
  6  /

Out of interest, do you get any further back if each error message is shorter (e.g. a shorter procedure name)? From a quick test, SQLERRM is limited to 510 characters (doubtless documented somewhere though I can't find it just now) - the documentation says FORMAT_ERROR_BACKTRACE is not subject to the same size limitation, but that doesn't mean there is no size limitation.
