Invalid polyhedron error with diagonal geometry

[akakikuumeri]

I'm trying to create a rectangular burr piece with a diagonal wedge. Some combinations of diagonal geometry components result in the error below.

This renders fine:

["x{components={z-,x+,y-z-,y-x+,y+z-,y+x+}}x"]

But add some voxels around the wedge:

["x{components={z-,x+,y-z-,y-x+,y+z-,y+x+}}x|x.",".x"]

And the following error results:

ERROR: Assertion 'is_3_vector(p)' failed: "Invalid polyhedron: [[7.62, 7.62, -6.91289], [22.1529, 7.62, -6.91289], [22.1529, 7.62, 22.1529], [8.32711, 7.62, 22.1529], [nan, nan, -inf]]" in file ../OpenSCAD/libraries/puzzlecad/puzzlecad-polyhedra.scad, line 79 TRACE: called by 'make_poly', in file ../OpenSCAD/libraries/puzzlecad/puzzlecad-polyhedra.scad, line 594.

I'm having the same problem, any workaround?

It seems like the problem occurs in the beveling logic, so I'm currently working around it with $burr_bevel = 0;, which obviously won't work for every use case.
