8468,Compile error on visual studio 2010/2012 using vector with custom allocator and aligned types,Rosario Leonardi <rosario.leonardi@…>,Ion Gaztañaga,"Using boost containers with an allocator that have a construct function I have an error saying that the type can't be aligned.
This is caused by boost trying to check if is possible to call construct with the parameter that i pass.
In has_member_function_callable_with_construct_impl it try to do something like that:

{{{
template<typename Fun>
struct funwrap2_construct
	: Fun
{
	funwrap2_construct();

	using Fun::construct;
	private_type construct(dont_care& , dont_care&)  const;
};


struct testConstruct
{
    typedef funwrap2_construct< Foo > FunWrap;

    static bool const value = 
		sizeof(no_type) == sizeof(is_private_type(  (std::declval< FunWrap > ().construct(std::declval<MyObj *>(), std::declval<const MyObj&>() ), 0)));
};
}}}
where MyObj is my aligned class and dontcare is an empty class with ellipse constructor.
Ellipse can't be reference and that's why visual studio thinks that FunWrap::construct will use an aligned parameter passed on the stack.

struct dont_care should have a templated constructor like boost::any.",Bugs,closed,To Be Determined,intrusive,Boost Release Branch,Problem,fixed,,
