发生异常。使用 C 和 SDL EXC_BAD_ACCESS（code=1，address=0x0）

问：

我在尝试使用功能将SDL_TEXTURE*分配给另一个SDL_TEXTURE*时出现EXP_BAD_ACCESS错误。

我正在使用 VSCode 在 macOS Sonoma 14.1 上使用 clang 进行编译。

我尝试使用 malloc 将内存分配给 fps_texture->texture，但这导致了同样的错误。

在 main.c 中

GAME_TEXTURE* fps_texture = NULL;
fps_texture->texture = text_load(app.renderer, fps_font, "TEST"); // Getting error here
if (!fps_texture->texture)
{
   printf("Unable to load font into texture!\n");
}

text_load定义

SDL_Texture* text_load(SDL_Renderer* renderer, TTF_Font* font, char* text)
{
  SDL_Texture* texture = NULL;

  //Render text surface
  SDL_Surface* text_surface = TTF_RenderText_Solid(font, text, TEXT_COLOR);
  if (text_surface == NULL)
  {
    printf( "Unable to render text surface! SDL_ttf Error: %s\n", TTF_GetError());
  }
  else
  {
    //Create texture from surface pixels
    texture = SDL_CreateTextureFromSurface(renderer, text_surface);
    if (texture == NULL)
    {
      printf( "Unable to create texture from rendered text! SDL Error: %s\n", SDL_GetError() );
    }
    else
    {
      //Get image dimensions
      // text_texture->width = text_surface->w;
      // text_texture->height = text_surface->h;
    }

    //Get rid of old surface
    SDL_FreeSurface(text_surface);
  }
  
  return texture;
}

结构体定义

typedef struct GAME_TEXTURE
{
  SDL_Texture* texture;
  uint32_t width;
  uint32_t height;
} GAME_TEXTURE;

为什么无法访问内存？
