> I found that it was an overflow in the glue code (now fixed) that converts the exact rationals coordinates of the output mesh, for which we prove the specification, to floats
Preserving the topology of mesh intersections while rounding the coordinates is a hard problem. In particular, it is only in 2020 that an algorithm was found that handles all the cases [1]. In practice, an efficient algorithm for that was published last year [2].
