This is because iterators may well be not plain pointers. Newer gcc's
use __normal_iterator<> instead of plain pointers for the standard
containers. If you look in
/usr/include/c++/3.2.3/bits/stl_iterator.h:565

  // This iterator adapter is 'normal' in the sense that it does not
  // change the semantics of any of the operators of its iterator
  // parameter.  Its primary purpose is to convert an iterator that is
  // not a class, e.g. a pointer, into an iterator that is a class.
  // The _Container parameter exists solely so that different
containers
  // using this template can instantiate different types, even if the
  // _Iterator parameter is the same.
  ...
  template<typename _Iterator, typename _Container>
    class __normal_iterator
  ...

This may fix the error, but I haven't perused you code well enough:

dummy1 = &*found;
