:mrdocs:

Deallocate a block of memory at the specified `p` address by returning it to the memory resource held by this allocator. Optionally specify the number of objects, `n`, to deallocate. The behavior is undefined unless `p` is the address of a block previously allocated by a call to `allocate` with the same `n` from a copy of this allocator having the same `value_type` and not yet deallocated.
