sdl2中的内存泄漏？

Question

我有一个简单的程序，只能通过sdl2创建窗口：

::SDL_Init(SDL_INIT_EVERYTHING);
auto window_ = ::SDL_CreateWindow("", 0, 0, 640, 480, ::SDL_WINDOW_OPENGL);

bool game_on = true;

while (game_on) {
  ::SDL_Event event;
  while (::SDL_PollEvent(&event)) {
    switch (event.type) {
    case SDL_QUIT:
      game_on = false;
      break;
    default:
      break;
    }
  }
}

::SDL_DestroyWindow(window_);
::SDL_Quit();

如果我使用address-sanitizer进行编译和运行，则输出如下：

==10545==ERROR: LeakSanitizer: detected memory leaks

Direct leak of 8192 byte(s) in 2 object(s) allocated from:
  #0 0x4e1838 in __interceptor_malloc (/home/andrej/Public/git/sdl_game/bin/sdl_game+0x4e1838)
  #1 0x7f3eb1a61faf  (<unknown module>)

SUMMARY: AddressSanitizer: 8192 byte(s) leaked in 2 allocation(s).

如何查看address-sanitizer检测到的内存泄漏。但是，如果我删除了最后一个字符串（:: SDL_Quit（）），则此消息消失了。为什么？
