在循环输出中重复使用矢量几次迭代后“已杀死”[关闭]

Question

我有一个循环，在开始时声明一个向量，通过push_back（）向它写入数据。在循环开始时，我将向量重新声明为大小0.代码在循环的几次迭代后给我“杀死”。任何人都可以告诉我重用这个载体的正确方法吗？

//forever loop
while (1) {

        std::vector < unsigned char * > image_vector(0);
        std::chrono::steady_clock::time_point now = std::chrono::steady_clock::now();

        // initialize variables
        steady_clock::time_point start_second = now;
        steady_clock::time_point start_next_second = now;
        steady_clock::time_point end_time = now + std::chrono::milliseconds(dT2 * 1000); // time to end capture sequence

        while (1) {

            // if start of current second past end_time exit loop
            if (start_next_second >= end_time) {
                cout << "Done capturing..." << endl;
                break;
            }

            // incriment by 1s for start of next second
            start_next_second += std::chrono::milliseconds(1000); //start of next second

            for (int y = 0; y < dT1; y++) {
                unsigned char * data = new unsigned char[Camera.getImageBufferSize()];
                Camera.grab();
                Camera.retrieve(data);
                image_vector.push_back(data); /**********Writing data to vector********/
            }

        }

        /* Save all images in vector to disk */
        int index = 1;
        for (std::vector < unsigned char * > ::iterator it = image_vector.begin(); it != image_vector.end(); ++it) {
            std::stringstream fn;
            fn << "images/[Pi]image";
            fn << index;
            fn << getExtension(Camera);
            saveImage(fn.str(), * it, Camera);
            cerr << "Saving " << fn.str() << endl;
            //delete[] * it;
            index++;
        }


        cout<< "Capture done, sleeping 5 seconds before next capture routine." << endl;
        usleep(5000000); //sleep 5 sec before next capture routine
}

删除delete[] * it;前面的两条虚线解决了这个问题。
