visual c++和SDL-访问冲突错误

我需要你的帮助。我整天都在想我为什么会犯这个错误，但我什么都没想到。我想让我的程序做的事情是拍摄一个png图像并将其切片成瓷砖，我可以稍后用来制作地图。那么，有人能帮我解决这个错误吗？

#include "SDL.h"  
#include "SDL_image.h"
#pragma comment(lib, "SDL.lib")
#pragma comment(lib, "SDLmain.lib")
#pragma comment(lib, "SDL_image.lib")
    int main(int argc,char *argv[]) {

    SDL_Init(SDL_INIT_EVERYTHING);

    SDL_Surface *screen = SDL_SetVideoMode(800, 600, 32, SDL_HWSURFACE | SDL_DOUBLEBUF);
    IMG_Init(IMG_INIT_PNG);
    SDL_Surface *mapTileSet;
    mapTileSet = IMG_Load("map.png");
    SDL_Surface *myTiles[4];
    for(int i = 0; i < 3; i++)
        myTiles[i] = SDL_CreateRGBSurface(SDL_HWSURFACE | SDL_SRCCOLORKEY, 32, 32, 32, 0, 0, 0, 0);
    for(int y = 0; y < 3; y++)
    {
        for(int x = 0; x < 3; x++)
        {   
             int slice_x = x * 32;    
             int slice_y = y * 32;    
             SDL_Rect srcRect;    
             srcRect.x = slice_x;    
             srcRect.y = slice_y;    
             srcRect.w = 32;   
             srcRect.h = 32;    
             SDL_Rect dstRect;    
             dstRect.x = 0;    
             dstRect.y = 0;  
             int i =  x + y * 4;
             SDL_BlitSurface(mapTileSet, &srcRect, myTiles[i], &dstRect);
        }
    }
    SDL_BlitSurface(myTiles[0], 0, screen, 0);
    SDL_Flip(screen);
    SDL_Delay(10000);

    IMG_Quit();
    SDL_Quit();
    return 0;
}
