1946,[type_traits] type_with_alignment fails on non-power-of-2 alignment,andysem@…,John Maddock,"The type_with_alignment template fails to compile if the alignment is not a power of 2. This is a possible situation at least with MSVC 9.0. The following class of a user-defined stream gets alignment of 12:

class my_stream :
    public std::ostream
{
public:
    typedef boost::function0< void > function_type;
    function_type m_function;
};

I've attached a reduced code sample with more comments and the compiler error message.

I suggest to add a fallback type_with_alignment type in case if the alignment is not a power of 2. This type should have the requested alignment. It may be achieved with the __declspec(align(n)) specifier.
