websocketpp/boost:SIGSEGV在端点上。获取连接（uri） 我正在研究C++中的Load TestApp，它旨在测试我们的音频服务器的流媒体能力。对于这个客户机，我使用websocketpp并遵循以下步骤

我总是接到一个信号

con = endpoint.get_connection(connection_string);

我的工作线程：：工作方法

主应用程序在伪代码中类似于此

namespace blah
{
    TestmanagerClass::run()
    {
        start (additional) threads until limit n is reached;
        call workthread::work() method of each thread;
        handle finished threads;
        goto 1;
    }
}

这是WorkThread:：work（），我用伪代码替换了身份验证代码

namespace blah {
void WorkThread::work()
{
    AudioStreamHandlerPtr handler(new AudioStreamHandler());
    websocketpp::client::connection_ptr con;
    websocketpp::client endpoint(handler);

    try
    {
        // authenticate
        // get login/access token from webservice

        if( !worksOutFine )
        {
            logError();
        }
        else
        { // got access token :D

            // now obtain session token from session service

            if( !worksOutFine )
            {
                logError();
            }
            else
            { // process this session's calls

                std::string connection_string = "ws://localhost";//boost::str(boost::format("ws://%1%/data?user_id=%2%&session_token=%3%") % serverAddressNoPort % session_.userId % sessionToken);
                std::cout << "CONNECTIONSTRING " << connection_string << std::endl;
                con = endpoint.get_connection(connection_string);
                std::cout << "1" << std::endl;
                endpoint.connect(con);
                std::cout << "2" << std::endl;
                boost::thread t(boost::bind(& websocketpp::client::run, &endpoint, false));
                more code....
}
}

namespace无稽之谈{
void WorkThread:：work（）
{
AudioStreamHandlerPtr处理程序（新的AudioStreamHandler（））；
websocketpp:：客户端：：连接\u ptr con；
websocketpp:：客户端端点（处理程序）；
尝试
{
//鉴定
//从webservice获取登录/访问令牌
如果（！工作输出线）
{
logError（）；
}
其他的
{//已获取访问令牌：D
//现在从会话服务获取会话令牌
如果（！工作输出线）
{
logError（）；
}
其他的
{//处理此会话的调用
std:：string connection\u string=“ws://localhost”；//boost:：str（boost:：format（“ws://%1%/data？用户id=%2%&会话\u令牌=%3%”%）%serverAddressNoPort%session.userId%sessionToken）；
std:：cout当程序中只有一个客户端端点时，是否会发生此问题？例如，如果在TestmanagerClass:：run（）中只启动了一个线程它仍然崩溃吗？它不再发生了。它只是一个恶意构建的boost。我的一位同事在他的机器上重建了boost，并使用他的二进制文件，一切都很好。谢谢！
