No one said it needs to solve all "aliasing problems" (god knows what 
*exactly* that means). If you can make a list of "all the aliasing 
problems" we can go through it. But Ian posted a particular example, and 
my answer that if he puts TARGET on the array extra his example will be 
conforming and work on any conforming compiler still stands.

Not really. You simply fail to understand the difference between this 
example and other "aliasing problems". I would recommend you reread 
section and most notably the top of page 296 in 09-007r2.

When someone from outside the committee asks a question and there is an 
official answer we cannot disagree. This is what interps are for. If you 
want to argue that I can submit an interp and I can guarantee you my 
answer will be the official one?
