 If your design wants virtual dispatch into a derived class from a base class constructor or destructor for functions like `f` and `g`, you need other techniques, such as a post-constructor -- a separate member function the caller must invoke to complete initialization, which can safely call `f` and `g` because in member functions virtual calls behave normally. Some techniques for this are shown in the References. Here's a non-exhaustive list of options:

 ### <a name="Sd-dtor"></a>Discussion: Make base class destructors public and virtual, or protected and nonvirtual
 
 Should destruction behave virtually? That is, should destruction through a pointer to a `base` class should be allowed? If yes, then `base`'s destructor must be public in order to be callable, and virtual otherwise calling it results in undefined behavior. Otherwise, it should be protected so that only derived classes can invoke it in their own destructors, and nonvirtual since it doesn't need to behave virtually virtual.
 
 **Example**: The common case for a base class is that it's intended to have publicly derived classes, and so calling code is just about sure to use something like a `shared_ptr<base>`:

 Never allow an error to be reported from a destructor, a resource deallocation function (e.g., `operator delete`), or a `swap` function using `throw`. It is nearly impossible to write useful code if these operations can fail, and even if something does go wrong it nearly never makes any sense to retry. Specifically, types whose destructors may throw an exception are flatly forbidden from use with the C++ standard library. Most destructors are now implicitly `noexcept` by default.

 The behavior of arrays is undefined in the presence of destructors that throw because there is no reasonable rollback behavior that could ever be devised. Just think: What code can the compiler generate for constructing an `arr` where, if the fourth object's constructor throws, the code has to give up and in its cleanup mode tries to call the destructors of the already-constructed objects... and one or more of those destructors throws? There is no satisfactory answer.

 The `string`s of `v` are destroyed upon exit from `bad()` and so is `v` itself. This the returned pointer points to unallocated memory on the free store. This memory (pointed into by `p`) may have been reallocated by the time `*p` is executed. There may be no `string` to read and a write through `p` could easily corrupt objects of unrelated types.
