opencv 内存溢出，访问冲突

如下代码，每次运行均出现内存错误，而且可能不同；

 #include "stdafx.h"
#include <opencv2/opencv.hpp>

using namespace cv;
using namespace std;

int main()
{
    Mat image = imread("Sign.jpg", 1);
    if (!image.data)
    {
        printf("Cannot read the image!");
    }
    imshow("Sign.jpg", image);

    Mat grayImage;
    cvtColor(image, grayImage, CV_BGR2GRAY);
    vector<KeyPoint> keyPoints;
    FAST(grayImage, keyPoints, 55);
    int total = keyPoints.size();
    for (int i = 0; i < total; i++)
    {
        circle(image, Point((int)keyPoints[i].pt.x, (int)keyPoints[i].pt.y), 5, Scalar(0, 0, 255), -1, 8, 0);
    }
    imshow("Corners", image);
    waitKey();

    return 0;
}

同学你好，我把你的代码直接运行了一下，可以运行，不知道你报错报的是哪一个？是cannot read the image?
