Hello!
I tried sending an offending board file to JP Charras, but never heard
anything back, maybe it was blocked. If I plot gerbers from it, they
exhibit the problem with having self-intersecting polygons. Does anyone
else want to look at?
Here is a link to it:

Lorenzo, I'm not exactly sure what the 'butterfly' is that you mention I
should produce a summary test with. Can you explain?
This is a quad:

4 1
swap the node 1 and 4, twisting the polygon, and you have the butterfly:
3 2

\ /

4 1
AFAIK that's the simplest self intersecting polygon you can have. Also
the bane of all the polygon algorithms (it would be convex, too, anyway!)
