Re: [boost] [TR1] Test failures with VC9 + MS TR1

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?

Most strange, yes it looks like a bug to me, I mean the class is defininely polymorphic right? In any case *removing* a virtual destructor surely can't move a class from non-polymorphic to polymorphic ! :-) John.
