[CODE] Online Setting of Command Min_Levels

Hello list...

I've been trying to get the above mentioned thing coded, but I've run
into a few problems.  My guess is I'm probably not understanding how the
command_interpreter functions, but oh well...

My code exists as:
 char newcmd;
  sh_int newlev;

  half_chop(argument, buf, arg);

  if (!*buf || !*arg || !isdigit(*arg))
    send_to_char("Syntax: asdf <command> <newlevel>\r\n", ch);
  else {
    newcmd = strdup(buf);
    newlev = atoi(arg);

    if (arg <= 0)
    else {
      complete_cmd_info[newcmd].minimum_level = arg;
    log("%s %d", complete_cmd_info[newcmd].command,

When I fire off the command as "asdf kill 30", syslogs report:
Jul  3 10:27:07 :: Changed.
Jul  3 10:27:07 :: credits 29744

And sure enough, "credits" is set to a min level of 29744.  If I try it
again (asdf kill 30), the mud crashes.

Gdb reports the following:

#7  0x804978e in _start ()

I'm really stuck for clues (perhaps clueless) in this, but perhaps
someone else can see the problem(s)?

Any help received I'd be appreciative.
