It also seems that commonly is_valid will return intersection points that are not actually the correct intersection points in validity tests (not in testcase). Testcase: https://github.com/flippmoke/boost-geometry-is-valid-bug Thanks, Blake Thompson" Bugs closed To Be Determined geometry Boost 1.65.0 Problem fixed is_valid flippmoke@…
