In the implementation of rtree packing algorithm there is a wrapper around bounding box which is initialized on first call to a member function instead of in the constructor. It is also guaranteed that this function will be called because it relies on the R-tree node minimum number of elements which cannot be 0 (checked with assertions). This is by design, the box is initialized, in order to change it the algorithm would have to be redesigned. So this is false positive and can be closed. In Boost.Geometry it's also possible to enable debugging of point and box models implemented in the library (e.g. for box model representing R-tree nodes' bounding box) by #defining BOOST_GEOMETRY_ENABLE_ACCESS_DEBUGGING. So if you want to be sure if Boost.Geometry models used internally are initialized you can enable this in debug build.
