That's what the A argument is for. You quoted the wrong clause.

Oh, sorry. You mean this constructor: template shared_ptr(Y * p, D d, A a); A question: why is the API designed so that using a custom allocator forces the user to specify a deallocator? I.e. the two are orthogonal, so why force the (use A) => (must use D) implication? Is there a standard deleter class that can be just used in place of D?
