Hi,

Thanks for reporting this bug. We've fixed it, and the fix will be available in VC11. unique_ptr derives from empty deleters in order to take advantage of the Empty Base Class Optimization; we now use private inheritance to prevent the empty deleter's function call operator from being accessible to users of unique_ptr.

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