Comment:
Hi, thanks for your report.
One of your geometries is counter clockwise. Please use
boost::geometry::correct in that case. If done, the intersection is OK.
Producing the difference with a counter clockwise polygon is intentional -
it considers all of the outside as the polygon, and makes an intersection
with that all-of-the-outside with the polygon. This is the difference.
I resolve it as "invalid"
Regards, Barend
