Does the infinite recursion only happen using primitive types - and if so do you know why?
On MSVC (both 7.1 and 9.0), moving ::boost_swap_impl::swap_impl to ::boost::swap_impl introduces failures of the following tests from /trunk/libs/utility/swap/test/: - no_ambiguity_in_boost - primitive - specialized_in_std - std_typeinfo_ptr Borland 5.82 would have the following extra failures, after moving swap_impl to boost: - primitive - specialized_in_std - specialized_in_global - std_bitset - std_dateorder - std_string - std_typeinfo_ptr - std_vector_of_boost - std_vector_of_global - std_vector_of_other All of them are stack overflows. So far, I don't know why, exactly. BTW, here's the patch, adding extra checks to trunk/libs/utility/swap/test, checking if boost::swap does indeed exchange the values of its arguments. Hope you think it's okay... I wouldn't mind committing :-) Kind regards, Niels P.S. Isaac, I just added extra explanatory comments to trunk/boost/utility/swap.hpp. Please take a look: http://svn.boost.org/trac/boost/changeset/48171
