C++ 正在释放的curl\u easy\u opt throws EXE\u BAD\u访问或malloc指针未分配错误

我有时（并非所有时候）出现以下运行时错误

malloc:*对象0x14的错误：未分配要释放的指针 *在malloc\u error\u break中设置断点以进行调试

否则

EXE\U坏访问（EXC\U I386\U GPFLT）

在同一行代码上

请帮我解决这个问题

对于基于curl的服务器连接器，我有以下结构。 在curlBasedServerConnector.cpp中，查看此处出现>>错误的位置

curlBasedServerConnector.hpp

 class curlBasedServerConnector  : public webServiceConnectorInterfaceA
{

private:
    CURLcode curlCode;
    CURL* curlHandle;        
    char* messagePtr;
    std::string message = "";        
    static std::atomic<int> totalNumOfCurlProcesses;
    static std::atomic<bool> isGlobalInitCalledAlready;
    static std::mutex curlGlobalInitKey;   
    static size_t writeContents_s(char *buf, size_t size, size_t nmemb, void *up)
    {
        curlBasedServerConnector* pThis = static_cast<curlBasedServerConnector*>(up);
        return pThis->writeContents(buf, size, nmemb);
    }    
    // member version
    size_t writeContents(char* buf, size_t size, size_t nmemb)
    {
        std::copy(buf, buf+(size*nmemb), std::back_inserter(message));
        return size*nmemb;
    }

public:

    bool executeOperation()override ;

    bool openConnection() override;

    bool setHttpHeader(const char* contentType, const char* charSet)override;

    bool setServerUrl(const char* url)override;

    void setRequest(const char* request)override;

    void closeConnection() override;
    std::string getResponseAsString()override;

    bool listenToNotification()override;

    void setTrace(bool trace);

    int getNumberofCurlProcessesInitialized();

    curlBasedServerConnector()
    {       
        curlGlobalInitKey.lock();
        {
            if(!isGlobalInitCalledAlready)
            {
                curlCode = curl_global_init(CURL_GLOBAL_ALL);
                cout<<" Server Connector GLOBAL_INIT CALLED "<<endl;
                isGlobalInitCalledAlready = true;
                totalNumOfCurlProcesses++;
            }
            else
            {
                totalNumOfCurlProcesses++;            
            }            
        }
        curlGlobalInitKey.unlock();       
        openConnection();        
    }

    virtual ~curlBasedServerConnector(){

        curlGlobalInitKey.lock();        
        totalNumOfCurlProcesses--;        
        if(totalNumOfCurlProcesses == 0)
        {          
            curl_global_cleanup();      
        }        
        curlGlobalInitKey.unlock();      
    }  

};

我有一个访问器类，它组成了这个类，如下所示

class webServiceAccessor{
private:       
    const char* serverAddress = "http://localhost:2000";        
    std::shared_ptr<sharedQueue> gmsListenerQueue;
    std::shared_ptr<webServiceConnectorInterfaceA> webServiceConnectorInterface;

webServiceAccessor(){}
~webServiceAccessor(){}

curlHandle

似乎未初始化。据我所知，您正在将随机垃圾传递给

curl\u easy\u setopt

。谢谢，我已经解决了这个问题。并更改为curlHandle=NULL；它似乎工作得很好。由于错误出现在随机的时间点，我有点怀疑我的初始化。将curlHandle初始化为NULL是否有效？这是有效的，因为它使

openConnection

实际调用

curl\u easy\u init（）

。我打赌它以前没有这样做。对不起，我知道它在初始化为NULL之前起作用了。它只打开和关闭运行时错误。
