I have also made a minimal example so that anybody can test:
#include <iostream>
#include <boost/thread.hpp>
struct Runner {
                void operator()() const { std::cout<<"Runner::operator()\n"; }
};
int main(int, char*[]) {
        Runner r;
        boost::thread t1(r);
        t1.join();
        return 0;
}

Cheers,
