Boost ASIO Async_receive崩溃程序

Question

在大多数情况下，我的程序运行良好，但有时会崩溃。如果我在运行中暂停程序，它也会崩溃。关于为什么的任何见解将不胜感激！我认为这可能是由于async_read_some在实际执行之前被多次调用了。

Main.cpp：

while(true)
{
    sensor->update();

    if (sensor->processNow == 1)
    {
        sensor->process(4);
        sensor->processNow = 0;
        sensorReadyForUpdate = 1;
    }   
}

构造函数：

sensorHandler::sensorHandler(std::string host, int port, std::string name) :
socket_(ioservice_),
sensorAddress_(boost::asio::ip::address::from_string(host), port),
dataRequested_(false),
dataReady_(false)
{

}

更新功能：

bool sensorHandler::update()
{
ioservice_.poll_one();
if (inOperation == false)
{

    inOperation = true;

    socket_.async_read_some(boost::asio::buffer(receiveBuffer, receiveBuffer.size()), boost::bind(&sensorHandler::receiveCallback, this, _1, _2));
    return success;
}

}

接收回调函数：

bool sensorHandler::receiveCallback(const boost::system::error_code& error, std::size_t bytes_transferred)
{
    std::cout << "success - in receiveCallBack" << std::endl;
    processNow = 1;
    inOperation = false;
}

包括：

#include "sensorHandler.h"
#include <boost\bind.hpp>
#include <boost\asio\write.hpp>
#include <iostream>
#include <windows.h>

头文件：

class sensorHandler
{
public:
    sensorHandler(std::string host, int port, std::string name);
    ~sensorHandler();
    bool connect();
    bool update();
    boost::array<char, 400000> receiveBuffer;  // was 50000
}
