Was this issue discussed off list, or did it get overlooked?

In addition I would specify versions of Boost where this behavior appears. They are 1.48, 1.49 and 1.50beta.

Hi all, I have found the following problem.
There are two polygons in binary file in the attachment (One of them contents few thousands of points and their listing would be too long).
I use Visual Studio 2008 and this file was written by a program which was made by it.
The code presented in attachment read this file and try to intersect the polygons. The result is wrong. I see it even from analyzing bounding boxes: the bounding box of an intersection should be within (or equal to) the intersection of the bounding boxes of given polygons, but here it is not.
