I\'ve always assumed that an object begins and ends its lifetime in the same memory location, but I\'ve recently come across a scenario where I need to be sure. Specifically
What you are looking for is defined in [intro.object]/1
[...] An object occupies a region of storage in its period of construction ([class.cdtor]), throughout its lifetime, and in its period of destruction ([class.cdtor]).
This means the address cannot change as long as you can access it.
