For me, I think this is only a work around, the code snippet looks like below:

static void
cmd_qtstatus (char *packet)
{
  char *stop_reason_rsp = NULL;
  char *buf1, *buf2, *buf3, *str;
  int slen;

  /* Translate the plain text of the notes back into hex for
     transmission.  */

  str = (tracing_user_name ? tracing_user_name : "");
  slen = strlen (str);
  buf1 = (char *) alloca (slen * 2 + 1);
  hexify (buf1, str, slen);

  str = (tracing_notes ? tracing_notes : "");
  slen = strlen (str);
  buf2 = (char *) alloca (slen * 2 + 1);
  hexify (buf2, str, slen);

  str = (tracing_stop_note ? tracing_stop_note : "");
  slen = strlen (str);
  buf3 = (char *) alloca (slen * 2 + 1);
  hexify (buf3, str, slen);

  trace_debug ("Returning trace status as %d, stop reason %s",
	       tracing, tracing_stop_reason);

  if (in_process_agent_loaded ())
    {
      pause_all (1);

      upload_fast_traceframes ();

      unpause_all (1);
   }

  stop_reason_rsp = (char *) tracing_stop_reason;

  /* The user visible error string in terror needs to be hex encoded.
     We leave it as plain string in `tracing_stop_reason' to ease
     debugging.  */
  if (strncmp (stop_reason_rsp, "terror:", strlen ("terror:")) == 0)
    {
      const char *result_name;
      int hexstr_len;
      char *p;

      result_name = stop_reason_rsp + strlen ("terror:");
      hexstr_len = strlen (result_name) * 2;
      p = stop_reason_rsp = alloca (strlen ("terror:") + hexstr_len + 1);
      strcpy (p, "terror:");
      p += strlen (p);
      convert_int_to_ascii ((gdb_byte *) result_name, p, strlen (result_name));
    }

  /* If this was a forced stop, include any stop note that was supplied.  */
  if (strcmp (stop_reason_rsp, "tstop") == 0)
    {
      stop_reason_rsp = alloca (strlen ("tstop:") + strlen (buf3) + 1);
      strcpy (stop_reason_rsp, "tstop:");
      strcat (stop_reason_rsp, buf3);
    }

  sprintf (packet,
	   "T%d;"
	   "%s:%x;"
	   "tframes:%x;tcreated:%x;"
	   "tfree:%x;tsize:%s;"
	   "circular:%d;"
	   "disconn:%d;"
	   "starttime:%llx;stoptime:%llx;"
	   "username:%s:;notes:%s:",
	   tracing ? 1 : 0,
	   stop_reason_rsp, tracing_stop_tpnum,
	   traceframe_count, traceframes_created,
	   free_space (), phex_nz (trace_buffer_hi - trace_buffer_lo, 0),
	   circular_trace_buffer,
	   disconnected_tracing,
	   tracing_start_time, tracing_stop_time,
	   buf1, buf2);
}


There is a sprintf call with many parameters. I have no idea about %llx ????
