Hi,

Marcus Meissner showed me one case where tree-alias introduced an out of
bounds array reference that wasn't used at all. Hence the patch below to
suppress warnings about such artifically constructed cases.


I still would prefer you'd warn at dereference or escape sites only
(escape sites
are possible dereference sites).
