[sr-dev] Crash - auth

[Alex Balashov]

I had the following code as a register handler:

    t_check_request();

    if(!www_authorize("$td", "subscriber")) {

       switch($rc) {
          case -1:
             xlog(something about authentication error);
             break;

          case -2:
             xlog(something about invalid password);
             send_reply("403", "Forbidden");
             exit;

          case -3:
             xlog(something about invalid user);
             send_reply("403", "Forbidden");
             exit;

          default:
             xlog(something else)

       }

       www_challenge("$td", "1");
       t_release();
       exit;
    }


It worked fine with the initial 3.1.0 tarball from last week.  But it 
crashes with the tarball that is on the website right now:
