--- Comment #21 from Nikolay Sivov  ---
Didn't notice the test, sorry. I can confirm that it does show the problem. I
was able to reduce it further, this sequence shows the same infinite loop:

---
set_point(&point, 6.63999975e-01, 3.21999997e-01);
ID2D1GeometrySink_BeginFigure(sink, point, 0);
quadratic_to(sink, 6.63999975e-01, 2.22000003e-01, 6.30999982e-01,
1.48000002e-01);
quadratic_to(sink, 6.63999975e-01, 4.21999991e-01, 6.63999975e-01,
3.21999997e-01);
ID2D1GeometrySink_EndFigure(sink, 0);
