Re: [Boost-users] boost.type_traits - is_convertible issue with alignedtypes

A bug database search did not bring up any relevant matches, so I wonder if that is a new issue or just by design?

It's more a limitation of the current design - if the "To" template parameter is a type which can not be used as a function parameter (which is the case here), then the implementation won't compile - we can work around std conforming types that fall into that category, but not compiler specific extensions which have strange properties! Switching to the implementation to use the __is_convertible builtin fixes this issue BTW, but unfortunately causes other issue... HTH, John.
