The error you're getting is a known bug with lambdas, you can find multiple issues like it in bugzilla. > Note that the specifics of this example are only for demonstration > purposes--I'm not actually trying to use a custom deleter to perform > what the default implementation does. It's good that it's only for demonstration because your deleters have undefined behaviour, they mix the array form of 'new' with the non-array 'delete'. Usually the unique_ptr<T[]> specialization should be used for arrays.
