There's an extension to gcc which is Purify-like. Broadly, it does
what the original poster suggested, but does it within the compiler (I
seem to remember some machine-dependency, so presumably it does it at
a lowish level). It takes great care to allow mixtures of
checked/unchecked functions, which is a nice feature. If one were to
write yet another such tool, one should certainly read the
documentation that comes with the gcc add-on (a quick web search on
gcc+bounds+checking ought to find it)---it would surely give some
ideas.
