That's stating the obvious. ALL variables are deallocated when the program 
exits. ALL resources that are local to a process are freed when the 
process ceases to exist.

It's like:
void function()
{
    void *ptr = alloca(128);

    // Don't need to free ptr because it was allocated on the stack
}

or even:
void function()
{
    int i;

    // when this function exits, all variables allocated on the stack
    // will cease to exist
}

Yes, there are resources that might endure (shared memory blocks, files on 
disk, etc.), but those are the exception, not the rule.
