openssh unix dev - Mar 2002 - scp 's problem

I have add an authentication method to openSSH, I call it ICCAuthentication,
   much like RSAAuthentication, but the RSA private key is in the IC card.
   I did not change any source code of scp. I mean scp.c.
   I set all authentication methods to "no" in sshd_config but
ICCAuthentication yes.
   
   ssh works very well with this authentication method. But scp is not good with
it.
   scp always run_err() in the following context in scp.c:

   void sink(argc, argv)
   {
       ....
       .....
          if(first){
               run_err("%s",cp);
               exit(1);
          }
         ......
        ......
    }

    That means that "first" is always true. What does "sink"
mean anyway ?

    Why ?

    Thanks.

it should not be related to scp.
