克隆垫子时，OpenCV崩溃（是：这是OpenCV 3中的错误吗？）

Question

I have this code in opencv 3 which crashes:

int main(int argc, char *argv[])
{
   cv::Mat image1(100, 100, CV_8UC1);
   cv::Mat image2 = image1.clone();
}

This code crashes on clone line with this error:

 Unhandled exception at 0x00007FF62E41992B in test_aoolication.exe: 0xC0000005: Access violation reading location 0x000000000000000D.

Is it a bug in OpenCV 3 or I am doing something strange?

Answer 1

Based on some comments which reported they have no problem, I did more search and I found that the problem was I did not include opencv.hpp to my *.cpp file.

Interestingly, I did not get any compile time error and I was able to compile and run application.

So if you have strange behavior in openCV, make sure that you included to your code!
