运行时检查失败 #2 - 变量周围的堆栈'normalIndex'已损坏

我正在开发自己的个人游戏引擎，遇到了这个问题。试图加载OBJ文件以与DirectX一起使用，但LoadObjFile一直给我错误

Run-Time Check Failure #2 - Stack around the variable 'normalIndex' was corrupted.

我能做什么？有时变量名称会更改为"uvIndex">

这是我的代码：

const char* path,

std::vector < D3DXVECTOR2 > *textureVertices,
std::vector < D3DXVECTOR3 > *normals,

std::vector< unsigned int > *uvIndices,
std::vector< unsigned int > *normalIndices)
{
std::ifstream infile(path);  // construct object and open file
if (!infile) { 
std::cerr << "Error opening file!" << std::endl; 
return false;
}
std::string line;
while (std::getline(infile, line))
{
if (line.substr(0, 2) == "v ")
{
line = line.substr(2);                  // Eliminate line header
std::string buf;                        // Have a buffer string
std::stringstream ss(line);             // Insert the string into a stream
std::vector<std::string> substrings;    // Create vector to hold our words
while (ss >> buf)
substrings.push_back(buf);
D3DVECTOR vertex = { (float)atof(substrings[0].c_str()), (float)atof(substrings[1].c_str()), (float)atof(substrings[2].c_str()) };

}
else if (line.substr(0, 3) == "vn ")

值得注意的是，我使用的文件大约有300000个顶点。obj文件在这里http://tf3dm.com/3d-model/millenium-falcon-82947.html

这就是函数的调用方式(基于@O'Neil的评论

std::vector< D3DXVECTOR3 > vs;
std::vector< D3DXVECTOR2 > vts;
std::vector< D3DXVECTOR3 > ns;
std::vector< unsigned int > vertexIndices, uvIndices, normalIndices;
bool result = LoadObjFile("millenium-falcon.obj", &vs, &vts, &ns, &vertexIndices, &uvIndices, &normalIndices);
