As for the message for diagnostics (if we know that ...) we can generalize
it to warning: 'aNewItem' may be used uninitialized.  That's less precise
but does not contain funny pointer arith.  It would of course be bad to
do that for the generic tree dumpers.

But anyway, what's so strange about ‘*((void*)& aNewItem +8)’?  It was
invented exactly to avoid 'MEM[&aNewItem+8]'.
