AFAICT, the crash happens in the following block:

  /*
   * XXX
   * This entire block sorely needs a rewrite.
   */
        if (t &&
            ((t->inp_flags & INP_TIMEWAIT) =3D=3D 0) &&
            (so->so_type !=3D SOCK_STREAM ||
             ntohl(t->inp_faddr.s_addr) =3D=3D INADDR_ANY) &&
            (ntohl(sin->sin_addr.s_addr) !=3D INADDR_ANY ||
             ntohl(t->inp_laddr.s_addr) !=3D INADDR_ANY ||
             (t->inp_socket->so_options &
           SO_REUSEPORT) =3D=3D 0) &&
            (inp->inp_cred->cr_uid !=3D
             t->inp_cred->cr_uid))
          return (EADDRINUSE);
      }

more specifically, `t->inp_socket' is NULL. The top comment may not be
relevant, as it's been here for the past 8 years.
