Why does boost::asio::io_service not compile with std::bind?

I'm trying to compile simple test program with std::thread, std::bind and boost::asio using g++ 4.9.1 (-std=c++11).

However, when creating new thread, it doesn't compile, when I use std::bind. On the other hand, when I switch to boost::bind everything is fine.

Here's code:

#include <iostream>
#include <memory>
#include <thread>
#include <functional>
#include <boost/asio.hpp>
#include <boost/bind.hpp>

int main(int argc, char* argv[])
{
    boost::asio::io_service ioService;
    std::unique_ptr<std::thread> t;

    t.reset(new std::thread(std::bind(&boost::asio::io_service::run, &ioService)));
    //t.reset(new std::thread(boost::bind(&boost::asio::io_service::run, &ioService)));
    return 0;
}

Here's the error:

test.cpp: In function ‘int main(int, char**)’:
test.cpp:12:80: error: no matching function for call to ‘bind(<unresolved overloaded function type>, boost::asio::io_service*)’
    t.reset(new std::thread(std::bind(&boost::asio::io_service::run, &ioService)));

What am I missing?
