virtual void do_deallocate ( void * p, std:: size_t bytes, std:: size_t alignment ) = 0 ;		(since C++17)

Deallocates the storage pointed to by p .

p must have been returned by a prior call to allocate(bytes, alignment) on a memory_resource that compares equal to * this , and the storage it points to must not yet have been deallocated, otherwise the behavior is undefined.
