12106,Assertion in envelope() seems to be wrong,karsten,Barend Gehrels,"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.
