Hi,
i was checking if my code is compatible with c++98 standard and i've
encounterd compile error.  With -std c++11 option everything works
fine.
Below i've written code causing  same problem.

#include <boost/coroutine/coroutine.hpp>
#include <boost/coroutine/attributes.hpp>

typedef boost::coroutines::coroutine<void( boost::system::error_code ,
std::size_t)> coro_t;

struct coro_test{

    coro_test() {}

    void coro_fun(typename coro_t::caller_type& ca)const{
        boost::system::error_code ec;
        boost::tie(ec, boost::tuples::ignore) = ca.get();
        ca();
    }

    coro_t coro;
};

int main(int argc, char *argv[])
{

    {
    boost::system::error_code ec;
    coro_t coro2;    //default construction is ok
    coro_test ctest; //compile error ,  why ???
    coro_t coro( boost::bind(&coro_test::coro_fun, &ctest,
_1),coro_t::arguments( ec, 7));
    coro = coro_t(boost::bind(&coro_test::coro_fun, &ctest,
_1),coro_t::arguments( ec, 7));
    }
...

/usr/local/include/boost/type_traits/is_function.hpp:50: b³±d:forming
pointer to reference type
'boost::rv<boost::coroutines::coroutine<void(boost::system::error_code,
long unsigned int)> >&'

is not a member of
'boost::detail::is_function_impl<boost::rv<boost::coroutines::coroutine<void(boost::system::error_code,
long unsigned int)> >&>'

/usr/local/include/boost/type_traits/is_convertible.hpp:354:

I work with Qt, g++ compiler on ubuntu 12.10
Is this library bug ?
