Milestone: To Be Determined | Component: geometry
  Version: Boost 1.58.0 | Severity: Problem
 Keywords: |
------------------------------+---------------------------
 sym_difference(py1, py2, mpy) may return invalid multipolygons if the two
 polygons share parts of their borders, e.g. sym_difference of

   POLYGON((0 0, 0 1, 1 1, 1 0, 0 0))

 and

   POLYGON((1 0, 1 1, 2 1, 2 0, 1 0))

 See attached test case.
