Comment (by igaztanaga):

 Thanks for the report. I've tried to find a workaround with no luck. It's
 definitely a bug in the compiler, a really strange one. If your swap
 function is declared in a namespace the error disappears. The bug is
 present at least from Visual 2003.

 The error is triggered from
 boost/intrusive/detail/has_member_function_callable_with.hpp, which
 produces (for swap) the code

             template< class F
                   , std::size_t N =
 sizeof((boost::move_detail::declval<F>().swap (), 0))>
             struct zeroarg_checker_swap

 This ".swap()" call in the sizeof expression to use SFINAE to detect if
 the expression is correct seems to provoke the error. Sadly, I haven't
 found any workaround.
