为了跟踪一些难以重现的崩溃，我配置了UnhandledExceptionFilter来创建迷你转储文件，如下所述：Debugging Custom Filters For Unhandled Exceptions和Effective Minidumps
正在成功捕获转储，但解释堆栈信息的运气不佳。希望其他人也会遇到类似的情况，我将在下面提供尽可能多的详细信息。如果这个问题因此变得有点冗长，请原谅。
Visual Studio提供以下转储摘要：

查看发生异常的线程的堆栈，我们得到以下极短的调用堆栈：

msvcr90d.dll!6d69f824()     
    [Frames below may be incorrect and/or missing, no symbols loaded for msvcr90d.dll]  
--> Server.exe!CServer::LoadPageList()  Line 269 + 0x28 bytes   C++
    cccccccc()

应用程序中所有正确的线程都有清晰的堆栈，显示了对__RtlUserThreadStart的调用。例如：

mswsock.dll!_WSPRecv@36()  + 0x34ff bytes   
ws2_32.dll!_WSARecv@28()  + 0x71 bytes  
wsock32.dll!_recv@16()  + 0x33 bytes

崩溃线程堆栈的较低部分如何被0xCCCCCCCC替换？
为完整起见，此处为框架Server.exe!CServer::LoadPageList() Line 269 + 0x28 bytes的拆卸

• 最新情况 *

完全忘记了包括函数源代码（感谢Joachim）：

void CServer::LoadPageList()
{
    CString header;
    header.Format("Accept: text/plain, */*; q=0.01\r\n");
    _pSession->setHttpHeader (header);
    _pSession->ReadPage (_T("/Pages"), true);
    SaveTimeStampedFile ("Pages.txt");
}

奇怪的是，函数LoadPageList中的所有操作都成功完成了，崩溃似乎发生在字符串的析构函数被调用之后，就在从这个堆栈帧返回之前。
