Hi everyone,

I am having some trouble with CGAL circulators. I am stuck with an akward
segmentation fault. The gdb debugger informs that * operator fails to work.
But it doesn't happen systematically. The code usually manages to perform a
few iterations. Any ideas on what could be wrong or any advice on how to use
circulators? (I am using CGAL 3.6)

 if (circ == 0) {
    cerr << "ERROR: Unexpected error empty circulator" << endl;
    exit(-1);
  }
  Orientation minimun = none;
  Facet_circulator origin(circ);
  do {
    // operator * fails
    // Valgrind -> "Invalid read of size 8" Compact_container.h:808
operator*() const
    if (circ == 0) {
      cerr << "ERROR: Unexpected empty circulator" << endl;
      exit(-1);
    }
    Facet adj_facet = *circ;
    // Make sure adjacent facet is a surface facet
    map<Facet, int>::iterator iter = f_map.find(adj_facet);
    if (iter != f_map.end()){
      int adj_facet_pos = iter->second;
      Orientation dir = orientations[adj_facet_pos];
      minimun =  dir < minimun ? dir : minimun;
    }
  } while (++circ != origin);
