 Hi,

 the following code stops with an assertion. It seems that the check for
 the aequator in
 algorithms/detail/envelope/segment.hpp:compute_box_corners() is not
 correct.

 {{{
 #include <boost/geometry.hpp>
 #include <iostream>

 using namespace std;

 namespace bg = boost::geometry;

 typedef bg::cs::spherical_equatorial< boost::geometry::degree > cs_type;
 typedef bg::model::point< double , 2 , cs_type > point_type;
 typedef bg::model::box< point_type > box_type;
 typedef bg::model::segment< point_type> segment_type;

 int main( int argc , char *argv[] )
 {
     auto segment = segment_type { point_type { 11.488323611111111 ,
 53.687086666666673 } , { 11.488324166666667 , 53.687086666666673 } };
     auto box = box_type {};
     bg::envelope( segment , box );
     return 0;
 }
 }}}

 The problem does not occur in version 1.58 and earlier.
