C和D中的相同_exact_代码给出不同的结果 – 为什么？

int mainCRTStartup()

    MSG msg;
    HWND hWndParent;
    WNDCLASS wndClass =

        0,&DefWindowProc,NULL,LoadCursor(NULL,IDC_ARROW),GetSysColorBrush(COLOR_3DFACE),TEXT("MyClass")
    };
    RegisterClass(&wndClass);
    hWndParent = CreateWindow(
        wndClass.lpszClassName,WS_VISIBLE | WS_OVERLAPPEDWINDOW,33,100,NULL);
    CreateWindow(TEXT("Button"),wndClass.lpszClassName,WS_VISIBLE | WS_CHILD | BS_GROUPBOX,5,50,hWndParent,NULL);
    while (GetMessage(&msg,0) > 0)
    {
        TranslateMessage(&msg);
        DispatchMessage(&msg);
    }
    return 0;
}

我明白了：

但是当我运行等效的D代码时：

// Again,get rid of the runtime
pragma(startaddress,mainCRTStartup);
pragma(lib,"dmd_win32.lib");

import win32.windows;

int mainCRTStartup()
{
    MSG msg;
    HWND hWndParent;
    WNDCLASS wndClass =
    {
        0,"MyClass"
    };
    RegisterClass(&wndClass);
    hWndParent = CreateWindow(
        wndClass.lpszClassName,NULL);
    CreateWindow("Button",0) > 0)
    {
        TranslateMessage(&msg);
        DispatchMessage(&msg);
    }
    return 0;
}

我明白了：

我很困惑……有什么可能导致这个白色背景？！

编辑：

我不确定它实际上是一个库bug …我只是删除了依赖项(我没有看到代码有什么问题),但问题仍然存在：

要么我做错了,要么是编译器错误……但即使它是编译器错误,我仍然不知道这样的事情会发生什么,因为它需要调用非常具体的API！想法？
