malloc：对象的错误：未分配被释放的指针

Question

所以我在OpenCv v2.4.13.2中为MSER创建了一个JNI包装器。

离开Java进程运行大约5分钟后，我收到此错误：

java(658,0x7000070bb000) malloc: *** error for object 0x11921c6f0: pointer being freed was not allocated *** set a breakpoint in malloc_error_break to debug

这绝对是使用JNI，但我不确定究竟是什么导致了这个malloc错误，因为我对C ++并不十分熟悉。 我猜这是由于内存清除不当，但我不确定在哪里。

我文件中的相关代码：

MSER mser; // Global variable so that pointer useable by Java can be created

JNIEXPORT jlong JNICALL Java_org_opencv_features2d_MSER_create_11(JNIEnv* env, jclass cls, jint delta, jint min_area, jint max_area, jdouble max_variation, jdouble min_diversity, jint max_evolution, jdouble area_threshold, jdouble min_margin, jint edge_blur_size)
{
    static const char method_name[] = "MSSR::create_1";

    //LOGD("%s", method_name);

    mser = MSER::MSER(delta, min_area, max_area, max_variation, min_diversity, max_evolution, area_threshold, min_margin, edge_blur_size);

    return (jlong) &mser;
}

JNIEXPORT void JNICALL Java_org_opencv_features2d_MSER_detect_14(JNIEnv* env, jobject thiz, jlong self, jlong image_addr, jlong msers_addr, jlong mask_addr)
{
    static const char method_name[] = "MSSR::detect_4";

    try {
        //LOGD("%s", method_name);
        MSER* me = (MSER*) self;
        Mat image = *(Mat*) image_addr;
        vector<vector<Point> > msers; // List<MatOfPoint> -> Mat -> vector<vector<Point> >
        Mat mask = *(Mat*) mask_addr;
        me->operator()(image, msers, mask);
        vector_vector_Point_to_Mat(msers, *(Mat*)msers_addr); // Store vector data in Mat dummy to be converted to List<MatOfPoint>
    }
    catch (const exception &e) {
        throwJavaException(env, &e, method_name);
    }
    catch (...) {
        throwJavaException(env, 0, method_name);
    }
}

来自converters.cpp：

#define CHECK_MAT(cond) if(!(cond)){ return; }

void vector_vector_Point_to_Mat(std::vector< std::vector< Point > >& vv_pt, Mat& mat)
{
    std::vector<Mat> vm;
    vm.reserve( vv_pt.size() );
    for(size_t i=0; i<vv_pt.size(); i++)
    {
        Mat m;
        vector_Point_to_Mat(vv_pt[i], m);
        vm.push_back(m);
    }
    vector_Mat_to_Mat(vm, mat);
}

void vector_Mat_to_Mat(std::vector<cv::Mat>& v_mat, cv::Mat& mat)
{
    int count = (int)v_mat.size();
    mat.create(count, 1, CV_32SC2);
    for(int i=0; i<count; i++)
    {
        long long addr = (long long) new Mat(v_mat[i]);
        mat.at< Vec<int, 2> >(i, 0) = Vec<int, 2>(addr>>32, addr&0xffffffff);
    }
}

当我运行同一程序的多个实例时，这似乎也只会发生。 这可能意味着它与全局MSER mser变量有关。
