:mrdocs:

Give back, to the specified `allocator`, the block of raw memory at the specified `p` address having the specified `nbytes` size and optionally specified `alignment`. If `alignment` is not specified, the natural alignment for an object of size `nbytes` is used. The behavior is undefined unless `p` refers to a block having the same size and alignment previously allocated from a copy of `allocator` and not yet deallocated.
