Hi again,

 

Still working on some stuff with boost::geometry and stumbled upon another bug-like behavior.

Roughly, build two polygons (one outer ring each) check that they intersect, try to union them and end up with nothing (well, checking that they intersect beforehand is not even relevant).

 

 

I am using boost 1.54 and vertices xs and yx are extracted from the debugger. I guess using different compiler options might fix this issue. Unlike the bug with equals, I was not able to track the problem down in boost code. Again, I haven’t seem anything in the 1.55 changelog that indicates it is already fixed.
