* If more than one @c auto_ptr owns the same object at the same time the
* behavior of the program is undefined.
*
* The uses of @c auto_ptr include providing temporary exception-safety for
* dynamically allocated memory, passing ownership of dynamically allocated
* memory to a function, and returning dynamically allocated memory from a

* requirements for Standard Library <a href="tables.html#65">container</a>

* @c auto_ptr results in undefined behavior.
