Comment (by awulkiew):

 Thanks for the report! Unfortunately I don't have a machine with the same
 setup as yours and I was unable to reproduce the problem on msvc-10,
 mingw-gcc-4.8.0 (win7) and gcc-4.8.4, clang-3.4 (linux mint 17).

 Currently I don't have an idea why you're experiencing this issue.
 Could you perform some debugging?

 E.g. detect exactly for which insert the segfault occurs, then break in
 file `boost/geometry/index/detail/rtree/rstar/insert.hpp` at line 279 and
 see when `this` and the address of `internal_node & n` becomes invalid?
 Because it seems this is the problem, right? Or is this just some
 backtrace inaccuracy?

 In case the issue was related with the `memmove` itself could you in file
 `boost/geometry/index/detail/varray_detail.hpp` try to replace the line
 224 with

 {{{
 return std::copy(first, last, dst);
 }}}

 and see if the problem persists?
