I've asked about this (and a couple of other failures on the Visual C++ blog.
The MS response is @

To confirm i've got the right idea about the failure:
The test that's failing is using the tr1 basic_regex along with a boost traits
class. The boost traits class uses a bitset for the char_class_type, whereas the
MS version uses an int.
The failure is then because the MS regex can't handle a bitset as the
char_class_type, due to the lack of an operator&& ?

The only other failure outside type_traits that i haven't raised yet is in
result_of (http://tinyurl.com/5gg58e). I haven't used result_of and i'm not sure
what problem the failure indicates. Does anyone have any other thoughts about it?

Thanks,
