In this specific case, perhaps. malloc will typically return memory to the system only if that memory is at the end of the heap. If there is more memory after block to be released, it can't return the memory block, because it won't punch a whole into the heap. So as soon as you have more than one object, things become interesting. Different systems use different, enhance strategies, of course. For example, Linux glibc malloc will allocate "large" blocks through mmap (instead of sbrk), such blocks then can be returned individually.
