i isn't GC managed here. It's a stack variable. Returning
references to the stack is a no-no, because the stack will be
reused.

If i was actually GC managed, it would not be collected, because
there's a reference to it:
----
int* CreatePermanentInt() {
      int* i = new int;
      *i = 5;
      return i;
}
