boost::geometry::union_ empty result

Reported by: phelippeneveu@… Owned by: Barend Gehrels
Milestone: To Be Determined Component: geometry

Description

union_() sometimes return an empty result. It seems like there is a bug with union_() if some vertices are too close to each other. I inspected the polygons and they seem to be valid (no self intersections). I created a SHP file and WTK file with a few problematic polygons. The polygons are in pairs, and if you call union_() on each pair, the result will be empty.

I forgot to mention that I did my testing using version 1.61.0.
