Your Position typedef is a bit unusual and I think it is causing problems.
This line:

      if ((*this[i]) & (1<<j))

should really be:

      if (((*this)[i]) & (1<<j))

since [] has higher precedence than *. It is currently assuming
you want the ith element in an array of Position elements, when
you really want the ith element in the array of longs in the
Position. (I think!)

You'll probably have less problems if you use a struct for
Position instead.
