Freeing

Is there any real point in freeing memory these days? And I don't mean freeing memory for things that constantly grow and shrink in size. I mean freeing that one array that you malloc at the beginning of the program and you need it until the end of the program. What is the benefit of freeing it when it will be automatically freed by the operating system?

no, it'd be a security hole if your OS fails to provide the standard security features all programs rely on.  A program should reasonably expect that its memory is inaccessible to other users, no matter how or when the access attempt is made.
