我收到下标超出范围错误。这是它发生的功能：

//Load Object Function
int loadObejct(const char *fileName)
{
cout<<"soos";
vector<string*> coord;
vector<coordinate*> vertex;
vector<face*> faces;
vector<coordinate*> normals;
ifstream in(fileName);

if(!in.is_open())
{
    cout<<"no file";
    return 5;
}

char buf[400];

while(!in.eof())
{
    in.getline(buf, 400);
    coord.push_back(new string(buf));
    cout<<"loading";
}

我标记了我将其缩小到问题发生的区域。我正在编码的是 VS2012 和 c++/cli。如您所见，我正在尝试从 .obj 文件加载数据以渲染 3D 模型。这不是完整的程序。如果您看到我遗漏的东西，请告诉我。:-)
