Segmentation violation associated with TSocket::Recv

      Description

      I am able to reliably produce seg faults in a minimal TSocket example by simply sending 5 characters to the listening port.  To reproduce, run this in one session (root -b server.C):

      {
        auto ss = new TServerSocket(9090, kTRUE);
        auto sock = ss->Accept();
        char buf[1024];
        if(sock) sock->Recv(buf, 1024);
      }

      and this in another:

       

      echo 12345 | nc -v localhost 9090
      

      The same thing happens when using TSocket::Recv(TMessage *&mess) and the same thing happens with the net tutorial hserv2.C.

      The actual seg fault seems to be taking place in tobuf in Bytes.h.
