11575	Boost::Polygon insert(item, true) of polygon_set_data wrong	cybfly1@…	Lucanus Simonson	"Codes below shows the way ""o_full_set.insert(o_item, true);"" which works in 1_53 but the same codes not get the same result with the same input in 1_56.
And if i use ""o_full_set -= o_item;"", then it works fine.

oPrboundary : (0, 0) (1000, 0), (1000, 1000) (0, 1000)
insert one polygon into pinGroup:(500, 500) (600, 500) (600, 600) (500, 600)
