Just from looking at the error message this would seem to be a cut-and-dried case of bugs in the compiler. The "overloads" it is saying are ambiguous are identical, meaning they're really just one thing.
Yes, I noticed the same thing. I cannot try the code on other compilers at the moment, it would be great if anyone from this mailing list could do that and let me know...
Even assuming this is a MSVC bug, is there a workaround for it?
For what it's worth. On MSVC10 your code only fails to build in Debug mode for me. There's a Workaround already in requires.hpp that only triggers if BOOST_MSVC < 1300 or #ifdef(NDEBUG). Adding || BOOST_WORKAROUND(BOOST_MSVC, == 1600) (obviously 1600 is my _MSC_VER) gets rid of the problem for me. I don't know why the workaround has been disabled for debug builds and I don't know if enabling it that way wreaks havoc somewhere else. Have a nice day, Stefan #if defined(NDEBUG) || BOOST_WORKAROUND(BOOST_MSVC, < 1300) || BOOST_WORKAROUND(BOOST_MSVC, == 1600) # define BOOST_CONCEPT_REQUIRES(models, result) \ typename ::boost::parameter::aux::unaryfunptr_arg_type<void(*)result>::type
