So I am having this error with my code and keep getting the Stack Overflow Error and cannot fix it no matter what I try. I was hoping someone could point out what is wrong.

 

Here is my model loading and drawing code:

 

////MODEL.CPP

#include "model.h"

Model::Model()
{
}

Model::~Model()
{
}

void Model::Load(LPCSTR Filename, LPDIRECT3DDEVICE9 GraphicsDevice)
{
    HRESULT HR;
    HR = D3DXLoadMeshFromX("Content/m.x", D3DXMESH_SYSTEMMEM,
        GraphicsDevice, NULL, &MaterialBuffer, NULL, &MaterialCount,
        &Mesh);
    if (FAILED(HR))
        MessageBox(NULL, "Can't load model!", "ERROR", MB_OK);
    Materials = (D3DXMATERIAL*)MaterialBuffer->GetBufferPointer();
    MeshMaterials = new D3DMATERIAL9[MaterialCount];
    MeshTextures = new LPDIRECT3DTEXTURE9[MaterialCount];
    for (DWORD i = 0; i < MaterialCount; i++)
    {
        MeshMaterials = Materials.MatD3D;
        MeshMaterials.Ambient = MeshMaterials.Diffuse;
        MeshTextures = NULL;
        if (Materials.pTextureFilename)
            D3DXCreateTextureFromFile(GraphicsDevice,
            Materials.pTextureFilename, &MeshTextures);
    }
    MaterialBuffer->Release();
}

void Model::Render(LPDIRECT3DDEVICE9 GraphicsDevice)
{
    D3DXMATRIX World;
    D3DXMatrixIdentity(&World);
    GraphicsDevice->SetTransform(D3DTS_WORLD, &World);
    for (DWORD i = 0; i < MaterialCount; i++)
    {
        GraphicsDevice->SetMaterial(&MeshMaterials);
        GraphicsDevice->SetTexture(0, MeshTextures);
        Mesh->DrawSubset(i);
    }
}

 

////MODEL.H

#ifndef _MODEL_H_
#define _MODEL_H_
#include <d3d9.h>
#include <d3dx9.h>

class Model
{
    public:
        Model();
        ~Model();
        LPD3DXMESH Mesh;
        LPD3DXBUFFER MaterialBuffer;
        DWORD MaterialCount;
        D3DXMATERIAL* Materials;
        D3DMATERIAL9* MeshMaterials;
        LPDIRECT3DTEXTURE9* MeshTextures;
        void Load(LPCSTR, LPDIRECT3DDEVICE9);
        void Render(LPDIRECT3DDEVICE9);
};

#endif

 

Does anyone spot why this would be calling a stackoverflow error?

Do we get to know where the stack overflow occurs?

 

Also, where is the code that calls the function that is throwing the stack overflow?
