Problem with intersection

[Rusanimal]

Hello. I have a problem with polygon intersections.
Normal

Bad

Bad

Coordinates of one point change.
Did I get a bug or is it some kind of feature?

The problem with the line. If divided, it works correctly

It will be hard to debug without coordinates @Rusanimal - any chance you could supply some?

There is a note somewhere in the Martinez paper that the algorithm doesn't like inputs that have overlapping segments, which your inputs do...

I'm not sure if there is a way around this limitation - can you try out the polygon-clipping library and see if that is able to give a result?
