To take care of the trouble, either increase the life span of the object the pointer is intended to confer with, or shorten this hyperlink the lifetime in the pointer (transfer the dereference to ahead of the pointed-to object’s life span finishes).
For the foundation class Foundation, contacting code could possibly make an effort to wipe out derived objects through tips to Foundation, including when utilizing a unique_ptr. If Base’s destructor is community and nonvirtual (the default), it might be unintentionally identified as on a pointer that actually points to the derived object, by which circumstance the actions from informative post the attempted deletion is undefined.
