栈不平衡与调用约定1. 初步分析某进程崩溃必现。打开崩溃dmp，结合c++源代码，崩溃大致发生在某dll代码里的这句：SAFE_DELETE(pContentData);En_HP_HandleResult CTcpOperation::OnClintReceive(HP_Client pSender, HP_CONNID dwConnID, const BYTE * pdata, int iLength) { LOG_INFO(_T("Client OnReceive iLength is %d"), iLength); if (iLength == sizeof(STcpTransferData)) { LPVOID pVoidTemp = nullptr; STcpTransferData cTransferData; memmove(cTransferData, pdata, sizeof(STcpTransferData)); if (CTcpOperation::GetInstance()-CheckAndSetData(ETransferType::SenddataLength, cTransferData, dwConnID, pVoidTemp))//单条数据总大小
