Segmentation fault when using example sherrif_puzzle about nonogram

Hm, thats weird, it works for me just as fine as the others.
Anyways, thank you for the overall effort, it is of course very welcome :)

(attilaszia: no need to read this, this is a note for myself)

Found the cause:

bool Table::Init(std::string filename){
  std::cout << "Initializing a table with " << filename << "\n";
  std::ifstream f;
  std::string line;
  f.open(filename.c_str());
  assert(f.is_open());
  
  int lastindex = filename.find_last_of("."); 
  raw_filename_ = filename.substr(0, lastindex); 
  
  if ( f.is_open() ) {
    if ( getline (f,line) ){
      
      std::stringstream  linestream(line);
      // Setup width, and height 
      linestream >> width_;
      linestream >> height_;

      assert(height_ > 0);
      assert(height_ < 1'000'000'000);
    }
    // Setup cols 
    for (int i=0; i<width_; i++){
      getline (f,line);
      std::vector<int> linedata; 
      std::stringstream linestream(line);
      int value;
      while ( linestream >> value ) {
        linedata.push_back(value);
        assert(linedata.size() < 1'000'000);
      }
      assert(height_ > 0);
      assert(height_ < 1'000'000'000); //HERE
      Line* current_col = new Line(linedata, height_);
      current_col->set_type(kColumn);
      current_col->j(i);
      cols_.push_back( current_col );
      heap_.push( current_col );
    }
  //...
}

Leading hypothesis:

• Windows file format used in the text files

Works now locally and on Travis, without any bug actually found. May be a Heisenbug. Close anyways.
