疑似std::regex_search正则匹配，导致堆栈错误

　　一个很奇怪的问题，当我_beginthreadex/CreateThread创建线程，使用std::regex_search匹配时，程序会崩溃，堆栈如下：

　　但是当我不在CreateThread创建的线程中匹配，在程序主线程去匹配，就不会出现这个问题，很纳闷，怀疑是std::regex_search匹配导致了线程堆栈问题，暂时记录一下

　　最后改用boost库了，就没有这个问题了

　　

            std::string_view  view((char*)pScanObject1->pFileMapAddress, (size_t)pScanObject1->ullFileMapSize);

using SVMatchResults = std::match_results< std::string_view::const_iterator >;
        SVMatchResults mm;
        if (std::regex_search(view.begin(), view.end(), mm, re)) 
        {
            std::cout << "matches!\n";
            //return 0;
        
        }
