I encounter the issue when TrackGOTURN sample code crash
System information (version)
OpenCV =\> 4.7.0
Operating System / Platform =\> Windows 64 Bit
Compiler =\> Visual Studio 2019
Description
I get errors when running the application:
```auto
Ptr tracker2 = TrackerGOTURN::create();
VideoCapture video2("chaplin.mp4");
if (!video2.isOpened())
{
cout << "Could not read video file" << endl;
return EXIT_FAILURE;
}
Mat frame2;
if (!video2.read(frame2))
{
cout << "Cannot read video file" << endl;
return EXIT_FAILURE;
}
Rect bbox2(0, 0, 10, 10);
tracker2->init(frame2, bbox2);
while (video2.read(frame2))
{
bool ok = tracker2->update(frame2, bbox2); <-- sample application crashed!!!!!

```
When I run the application in release mode, there is no problem.
but when I run the application in debug mode, I face the crash

btw, those INFO messages are only shown in DEBUG mode
(that’s normal, and unrelated to whatever problem there is with goturn)

what exactly happens ? any output/msg ?

Thank you for the comment.
My sample code crashed in debug mode, but works well in release mode.
I don’t know what the problem is.
