It looks like Tracer::_result_ptr is NULL. You should trigger the ray tracing 
by calling one of the analysis function before calling get_trace_result(). 
Maybe it would be great to have a public function for starting the ray trace 
directly on the Analysis classes.

Use the const version of the get_tracer() function if you do not want the 
result to be invalidated:

const_cast<const 
Analysis::Spot&>(spot).get_tracer().get_trace_result().get_intercepted(image).size();
