MemPtrFree disposes a non-movable chunk of memory. After you free the
memory, what makes you think that you can later use the pointer to that
memory? (A: you can't, unless the memory hasn't yet been over-written with
something else.)
If you use a gadget to store a pointer to some data, you should make sure
that the data it is pointing to remains unchanged as long as you need it.
