List,
this paper explains how a compiler can eliminate from the final binary the
pointer safety checks that are present in the source code:
http://pdos.csail.mit.edu/~xi/papers/stack-sosp13.pdf
The very first example it gives is equivalent to the contents of TTEST2 macro
widely used in the source code of tcpdump. Even if subsequent 15 pages of the
analysis don't apply, it may make sense to study the solutions the paper
suggests.
