#12287: rtree.query(bgi::contains(point), std::back_inserter(result)) fails
---------------------------------+---------------------------
 Reporter:  martin.liebenberg@…  |      Owner:  barendgehrels
     Type:  Bugs                 |     Status:  new
Milestone:  To Be Determined     |  Component:  geometry
  Version:  Boost 1.61.0         |   Severity:  Problem
 Keywords:  index, rtree         |
---------------------------------+---------------------------
 When adding several points to an rtree, a query with bgi::contains(point)
 fails for some of these points. The reason seems to be that
 rtree.insert(point) expands a box in the rtree in
 boost/geometry/algorithms/expand.hpp so that the coordinate of a point can
 lie on the edge of a box. A query with bgi::contains(point) then checks
 with boost::geometry::strategy::within::within_range::apply(Value1 const&
 value, Value2 const& min_value, Value2 const& max_value) value > min_value
 && value < max_value so that a point on the edge of a box is not captured.
 The probability of the concurrency of this failure depends on the number
 of inserted points and the template value of the compile-time parameters
 of rtree as for instance in bgi::linear<32>. The greater the template
 parameter, the more points can be added until the failure occurs.
