我创建了客户端应用程序。当我发送单个消息 client <=> sever 时它工作正常。但是当我出于性能目的发送大量消息时，客户端会以两种不同的方式崩溃:

TCPSocketBody::~TCPSocketBody()
{
    delete [] data_to_read;
}

如有任何帮助，我将不胜感激。

最佳答案

socket_.close();

运行时抛出异常!

您可以使用 boost::system::error_code 来正确捕捉错误:

boost::system::error_code lErrorCode;
socket_.close(lErrorCode);
std::cout <<  lErrorCode.message() << std::endl;
