Subject: We still need to cast the resulting pointer in NEW and NEW2 as it
X-Git-Url: http://artulab.com/gitweb/?a=commitdiff_plain;h=fc2da2167d43a177115db568ab0a094e4c1cd71a;p=openbsd

We still need to cast the resulting pointer in NEW and NEW2 as it
is used in pointer arithmetic.  Otherwise we do arithmetic on void
* and corrupt the heap.
