 I get the following warning when I compile .cu files which uses the
 boost/core/swap.hpp file:

 {{{
 ~/sw/boost/include/boost/core/swap.hpp(36): warning: calling a __host__
 function from a __host__ __device__ function is not allowed
           detected during:
             instantiation of "void boost_swap_impl::swap_impl(T &, T &)
 [with T=boost::signals2::detail::foreign_shared_ptr_impl_base *]"
 (56): here
             instantiation of "void boost::swap(T1 &, T2 &) [with
 T1=boost::signals2::detail::foreign_shared_ptr_impl_base *,
 T2=boost::signals2::detail::foreign_shared_ptr_impl_base *]"
 ~/sw/boost/include/boost/signals2/detail/foreign_ptr.hpp(111): here
 }}}

 I get this even with the most recent git version (commit 3a94cde). The
 attached program gives this error when compiling like this:

 {{{   nvcc -I ~/sw/boost/include test_swap.cu}}}

 I use CUDA 7.5 and g++ 4.9.2.
