You drop deep into the magic that is the runtime on this one.
I would imagine you would have to cause heap fragmentation (and a re-order)
to get this to occur. I am unaware of a deterministic way to have this
happen but I assure you that someone much more in depth with the CLR has
written a blog post. I would check the CLR member blogs to see if you might
be able to find this.
I will try poking around a bit later to see if I can find one .. never had
to do this before but it is interesting :)

Thanks for your reply. I think I understand why it shouldn't be used,
(managed code shifts the address around) but in practice, I can't seem to
get
it to cause any erroneous results. What situation could cause a problem.
i.e.
How could I set this up to actually see a problem occuring. I've tried it
by
incrementing a local variable but can't seem to see any problems.
It's no big deal but I'm just curious.
Thanks anyway for your ideas & the link.
