    Description

          Records::const_iterator it = records.lower_bound(startingPosition);
          if (it == records.end() || it->first > startingPosition)
              --it;
       
          return it->first;
      

      This loop should first check that it != records.begin(). Otherwise --it will fall off the front of the map.
