爲什麼我的64位C++應用程序崩潰？

我寫了一個非常小的64位應用程序，它在乾淨的Windows Vista x64安裝上崩潰。它在安裝了Visual Studio 2008的開發計算機（Windows 7 64位）上運行平穩。爲什麼我的64位C++應用程序崩潰？

64位C++應用程序（非託管）由32位.NET應用程序啓動，並在出現訪問衝突錯誤後立即崩潰。這是事件查看器說：

Faulting application MaxTo64.exe, version 0.0.0.0, time stamp 0x49a41d9e, 
faulting module USER32.dll, version 6.0.6001.18000, time stamp 0x4791adc5, 
exception code 0xc0000005, fault offset 0x00000000000236d6, process id 0x82c, 
application start time 0x01c996a346a3e805. 

MaxTo64.exe 
0.0.0.0 
49a41d9e 
USER32.dll 
6.0.6001.18000

c0000005 
00000000000236d6 
82c 
01c996a346a3e805

我已經安裝了VC2008可再發行（2008年86，2008年64位，2008 SP1 x86和2008 SP1 64位），所以這不應該成爲問題。編輯：可能值得一提的是，在安裝vcredist-package之前，它會以不同的方式崩潰，並且存在並行配置錯誤。

我是一個C++ n00b，所以我真的不知道在哪裏看下。

在這一點上，調用堆棧：

USER32!ChangeWindowMessageFilter+0x12d 
USER32!RegisterClassExW+0x25

kernel32!BaseThreadInitThunk+0xd 
ntdll!RtlUserThreadStart+0x21

這似乎是在MyRegisterClass，它看起來像這樣：

ATOM MyRegisterClass(HINSTANCE hInstance) 
{ 
WNDCLASSEX wcex; 

wcex.cbSize = sizeof(WNDCLASSEX); 

wcex.style   = CS_HREDRAW | CS_VREDRAW; 
wcex.lpfnWndProc = WndProc; 
wcex.cbClsExtra  = 0; 
wcex.cbWndExtra  = 0; 
wcex.hInstance  = hInstance; 
wcex.hIcon   = LoadIcon(hInstance, MAKEINTRESOURCE(IDI_MAXTO64)); 
wcex.hCursor  = LoadCursor(NULL, IDC_ARROW); 
wcex.hbrBackground = (HBRUSH)(COLOR_WINDOW+1); 
wcex.lpszClassName = szWindowClass; 
wcex.hIconSm  = LoadIcon(wcex.hInstance, MAKEINTRESOURCE(IDI_SMALL)); 

return RegisterClassEx(&wcex); 
}

編輯：原來，問題是我自己愚蠢的錯誤。顯然，WNDCLASSEX結構中有一個字段未正確初始化。奇怪的是，這在Vista上崩潰，但在Windows 7上崩潰。添加這個可以解決問題。
