I think I have nailed down the underlying problem.

In case `EndFigure` is called with D2D1_FIGURE_END_OPEN, and the last vertex
(point) is coincident with the first one of the figure, later calculations
fail.

As the last segment then has an undefined direction and a length of 0, causing
the `nan`s seen.

Omitting the last segment when it has zero length fixes the problem. This is
already explicitly done when D2D1_FIGURE_END_CLOSED is set.

Anyone who is using openSUSE and wants to give it a try can check:
