Thanks.

Following on with the type_traits failures with is_polymorphic
(http://tinyurl.com/6jq57y):

If you have:

class foo
{
public:
        virtual ~foo()
        {

        }
};

class bar : virtual public foo
{
public:
        virtual ~bar()
        {

        }
};

Then boost::is_polymorphic<bar> is true, but mstr1::is_polymorphic<bar> is false.

If i either:
-make foos destructor non-virtual
-add an additional virtual method to bar
-change the defintion of bar to 'class bar : public foo'

then mstr1::is_polymorphic<bar> becomes true.
MS Bug?
