Comment:

 See attached file ticket_9828.cpp and its output in file ticket_9828.out.

 The output polygon is indeed open as you can see from the dsv output of
 the result, as well as from the number of points that I also print out.
 The WKT output/description (in develop branch or in the upcoming boost
 1.56) "closes" the polygon by default, so it is not a safe way for
 determining whether polygons are closed or not.
