This is definitely a C/C++ aliasing violation as you are first accessing it as
a MyHeap::Node and then as derived.
Here is how I would fix it for the first one I would change it to:
    void * newnode = malloc(bytes_needed);
    void *n = NULL;
    memcpy (newnode, &n, sizeof(n));
    Heads[bytes_needed] = newnode;

And use memcpy without a cast so you still have a "void*" and do the same for
the rest. and get rid of Node and just use void* instead.
