The best fix here is probably

    boost::bind( boost::type<void>(), f, a1 )

> 1) make_thread_info(boost::bind(f,a1))

This will fail when f is a function object without a result_type typedef.

> 2) make_thread_info(boost::bind<void>(mem_fn(f),a1))

This will fail when f is not a member pointer.

It seems that these will be exposed by test_thread_launching. It only misses 
the cases "ordinary function with arguments" and "member pointer".

The alternative syntax should work in all cases; can you please test it?
