Martin,
I'm guessing that the polygon ring is in fact closed, it's just that one
of the points is getting zeroed out for some reason.
It's hard to know what to say about where to start. But you could look
for convenient points where you could check whether the first/last point
of a ring is
Martin,
Thank you for confirming that. I will look at my code and validate that I am
not screwing up the points after the geos operation. If not, I will try my best
to debug through the geos source and look for the problem.
By chance do you have a recommendation on where I should start looking

This works fine in JTS.
Unfortunately I don't have GEOS running, so can't test it there.
Possibly we could look into that during some future work.
It is a bit suspicious that it looks like the offending point is the
terminating point of the last ring in the US MultiPolygon.
