That was not in the core general polygon booleans algorithm.  It was in the way the 45-degree algorithm was being used from the interface that normally calls the general polygon algorithm and the fact that general polygon formation wasn't compatible with the output of the 45-degree boolean in some cases.  There have been several bugs in Boost.Polygon since it was released, but none in the core boolean algorithms.
