Surface Matching never get any results with any data, why?

Question

Im trying to get working the Surface Matching Sample code from surface_matching. Im able to compile the code then when run with ./surface_matching /home/surface_matching/coke.ply /home/surface_matching/01.ply

Im running the same code sample as in the link. Code is the followving

#include "opencv2/surface_matching.hpp"
#include <iostream>
#include "opencv2/surface_matching/ppf_helpers.hpp"
#include "opencv2/core/utility.hpp"

using namespace std;
using namespace cv;
using namespace ppf_match_3d;

static void help(const string& errorMessage)
{
    cout << "Program init error : "<< errorMessage << endl;
    cout << "\nUsage : ppf_matching [input model file] [input scene file]"<< endl;
    cout << "\nPlease start again with new parameters"<< endl;
}

    if (argc < 3)
    {
        help("Not enough input arguments");
        exit(1);
    }

    vector<Pose3DPtr> results;
    tick1 = cv::getTickCount();

        result->printPose();
        if (i==0)
        {
            Mat pct = transformPCPose(pc, result->pose);
            writePLY(pct, "para6700PCTrans.ply");
        }
    }
    
    return 0;
    
}

It runs but never gets any results. I got this error

Segmentation fault (core dumped)

Training is complete and starts matching but then Segmentation fault. What can be the problem? Here the object model file: And the scene file

What can be the problem?
