双重释放或损坏错误c++

我有一个图形引擎的代码，它需要绘制线框和线条图，我对我的原始代码进行了一些调整，现在我得到了双倍的错误或损坏，但在代码正常工作之前，任何人都知道我做错了什么吗？

void Wireframe::Generate(list<eye_point> &points, list<line> &lines, const ini::Configuration &configuration)
{
    string buffer;
    stringstream out;
    for(int i = 0; i < nrFigures; i++)
    {
        figure = "Figure";
        out<<i;
        buffer = out.str();
        figure.append(buffer);
        out.str(string());
        cout<<"de figure heeft de naam "<<figure<<endl;
        Read_info(configuration);
        Generate_points(points, configuration);
        Generate_lines(lines, configuration);
    }
}

在读取信息中，他从ini文件中读取信息

void Wireframe::Generate_points(list<eye_point> &points, const ini::Configuration &configuration){
    Matrix schaal = Scale(scale);
    Matrix translate = Translatie(center);
    Matrix xrotate = Rotate_x_as(rotatex);
    Matrix yrotate = Rotate_y_as(rotatey);
    Matrix zrotate = Rotate_z_as(rotatez);
    Matrix eyematrix = Eye_transformatie(eye);
    Matrix matrix;
    matrix = schaal * translate * xrotate  * yrotate * zrotate * eyematrix;
    if(type.compare("LineDrawing") == 0)
    {
        linedrawing_point(points, configuration, matrix);
    }
    else if(type.compare("Cube") == 0)
    {
        cube_point(points,matrix);
    }
}
void Wireframe::Generate_lines(list<line> &lines, const ini::Configuration &configuration){
    if(type.compare("LineDrawing") == 0)
    {
        linedrawing_lines(lines, configuration);
    }
    else if (type.compare("Cube") == 0)
    {
        cube_lines(lines);
    }
}

在这里，他看到了他需要做的划线工作，划线工作很好，错误在立方体中。

void Wireframe::cube_lines(list<line> &lines){
    getline(lines, 1, 5);
    getline(lines, 5, 3);
    getline(lines, 3, 7);
    getline(lines, 7, 1);
    getline(lines, 5, 2);
    getline(lines, 2, 8);
    getline(lines, 8, 3);
    getline(lines, 3, 5);
    getline(lines, 2, 6);
    getline(lines, 6, 4);
    getline(lines, 4, 8);
    getline(lines, 8, 2);
    getline(lines, 6, 1);
    getline(lines, 1, 7);
    getline(lines, 7, 4);
    getline(lines, 4, 6);
    getline(lines, 7, 3);
    getline(lines, 3, 8);
    getline(lines, 8, 4);
    getline(lines, 4, 7);
    getline(lines, 1, 6);
    getline(lines, 6, 2);
    getline(lines, 2, 5);
    getline(lines, 5, 1);
}

    getpoint(1, -1, -1, points, 1, matrix );

    getpoint(1, 1, 1, points, 3, matrix );
    getpoint(-1, -1, 1, points, 4, matrix );
    getpoint(1, 1, -1, points, 5, matrix );
    getpoint(-1, -1, -1, points, 6, matrix );

    getpoint(-1, 1, 1, points, 1, matrix );

    vector_points *=  matrix;

    projectie(vector_points, point_element);
    points.push_back(point_element);
}
