C++ std::thread passing member function inside current class

Question

I am trying to make a thread call passing a member function. The problem is that I make the call inside another member function of the same class. What I mean:

class A {
   void foo(int a);

   void bar() {
       int k = 2;
       thread t(&A::foo, this, k);
   }
}

I also tried to pass this as reference: &this or std::ref(this) without any success. What exactly is my mistake?

EDIT: Below is the actual code that gives me the error

class SUBTHREAD {
public:
    SUBTHREAD(const SOCKET client, const int ID, MAINTHREAD *Server);

    void handleQFStreaming(const vector<string> &splitMessage);
    void handleIncoming(const string &message, const int &length);
    void run();

private:
    MAINTHREAD *Server;
    SOCKET client;
    vector<thread> QFSThreads;
    int ID;

};

void SUBTHREAD::handleQFStreaming(const vector<string> &splitMessage) {
     ...
}

void SUBTHREAD::handleIncoming(const string &message, const int &length) {
     ...
     QFSThreads.push_back(thread(&SUBTHREAD::handleQFStreaming, this, splitMessage));
     ...
}

EDIT: The entire error I get is:

Answer 1

The problem is

vector<thread> QFSThreads;

It is not allowed to copy a std::thread.
