Error on compiling template function of Queue of std::functions - c++

Question

I want to make a template function to queue both general functions and also class member functions. With internet search, I came up with the following code but have error in compiling it.
#include <iostream>
#include <functional>
#include <queue>
#include <string>
double MyFunction(double num1, double num2)
{
std::cout << "MyFunction( " << num1 << ", " << num2 << " )\n";
return num1 + num2;
}
class MyClass
{
public:
double MyClassFunction(double num1, double num2, double num3) const
{
std::cout << "MyClass::MyClassFunction( " << num1 << ", " << num2 << ", " << num3 << " )\n";
return num1 + num2 + num3;
}
};
struct MyFunctionQueue
{
template <typename FUNC, typename... ARGS>
void QueueFunction(FUNC fn, ARGS&&... args)
{
std::function<std::result_of_t<FUNC(ARGS...)> () > rFunc = std::bind(fn, args...);
_myFQ.push(rFunc);
}
void Execute()
{
while (!_myFQ.empty())
{
_myR.push(_myFQ.front()());
_myFQ.pop();
}
}
double PopResult()
{
double r = _myR.front();
_myR.pop();
return r;
}
std::queue<std::function<double()>> _myFQ;
std::queue<double> _myR;
};
int main()
{
MyFunctionQueue funcQue;
funcQue.QueueFunction(MyFunction, 1.234, 2.345);
MyClass obj;
funcQue.QueueFunction(&MyClass::MyClassFunction, std::ref(obj), 1.234, 2.345, 3.456);
funcQue.Execute();
std::cout << "MyFunction result: " << funcQue.PopResult() << std::endl;
std::cout << "MyClass::MyClassFunction result: " << funcQue.PopResult() << std::endl;
}
I know the error is with the template code generation on the class member function. With my limited knowledge in using templates I cannot figure out what's wrong with it. Can anyone help to point out the mistake in the code? And the error I've got from VC++ is:

Answer 1

So, I think this is an issue with vc++. Passing a member function works just fine when the next parameter is a pointer, but fails when it is a reference.
template <class F, class... A>
std::result_of_t<F(A...)> Foo::bar(F f, A... a)
{
return 0;
}
Foo f;
f.bar(&Foo::other_function, std::ref(f)); //error
f.bar(&Foo::other_function, &f); //success
Additionally, result_of in vc++ fails when the function type is a function (like void()), but clang and gcc both succeed.
template <class F, class... A>
struct Foo
{
typedef std::result_of_t<F(A...)> type;
};
Foo<int(int), int> //fails in only vc++
