https://svn.boost.org/trac10/ticket/12608 <p> I have one polygon set that was built from one polygon and I'm substracting other polygon set built from 17 polygons. assign operation passed successfully but then library is crashing on get operation when I'm trying to get vector with polygons with holes.
