Hi,

Thanks for reporting this bug. It's too late to fix this in VC10 (despite the fact that it's trivial, only truly major bugs are eligible to be fixed between RC and RTM), but we'll keep this bug open so that it can be fixed in VC11.

If you have any further questions, feel free to E-mail me at stl@microsoft.com .
