[geos-devel] Union problem

[Martin Chapman]

Unfortunately, I do not have JTS but I will try to step through the code and
see if I can learn more about the problem.  Perhaps a careful inspection of
the input and output point sets will yield some clues because the problem is
predictable.

Best regards,
Martin

Most probably a bug... any chance you could run this same test case
under JTS so we can confirm if it's a problem at the algorithm level
or the port level?

Thanks,
