为什么我的dll在__DllMainCRTStartup失败了？

Question

我不知道我的dll通常在函数__DllMainCRTStartup失败的原因？

这是我在gbkgw.dll中的代码：

BOOL APIENTRY DllMain( HMODULE hModule,
                       DWORD  ul_reason_for_call,
                       LPVOID lpReserved
                     )
{
    UNREFERENCED_PARAMETER(hModule);
    UNREFERENCED_PARAMETER(lpReserved);

    switch (ul_reason_for_call)
    {
    case DLL_PROCESS_ATTACH:
    case DLL_THREAD_ATTACH:
    case DLL_THREAD_DETACH:
    case DLL_PROCESS_DETACH:
        break;
    }
    return TRUE;
}

这是我的gbkgw.dll转储崩溃文件：
