3395,Assignment to optional is not possible if operator& is overriden,Andrey Semashev,Fernando Cacciola,"The assignment operator for optional< T > uses T::operator& to dispatch the call between assign_expr functions. This dispatch breaks if the T::operator& returns something else than T*. This is the case with ATL types, such as CComBSTR.

The suggested fix is to replace call to operator& with addressof. Please, find the attached patch against the 1.40 release.
