Hi,

 

I just filed the following ticket:

https://svn.boost.org/trac/boost/ticket/9768

 

boost::geometry::difference should not add redundant points to a polygon. When I subtract an empty box from a polygon, the result ends up representing the empty box even though obviously it should  not.

 

If you have any questions regarding the issue, please do not hesitate to contact me.

Thank you

   Volker
