Detailed description
Calling cv::dnn::Net::dumpToFile on a loaded Darknet network gives SegFault.
Steps to reproduce
#include <opencv2/opencv.hpp>
#include <iostream>
using namespace cv;
using namespace dnn;
using namespace std;
int main(int argc, char* argv[])
{
String configPath = "network.cfg";
String modelPath = "network.weights";
Net net = readNetFromDarknet(configPath, modelPath);
cout << "Successfully loaded net, dumping to net.dot" << endl;
net.dumpToFile("net.dot"); // SegFault
return 0;
