If you can't cast from 'void *' to 'uintptr_t' and back, the language is no longer C any more. Indeed, with the added __bnd_* primitives, the language is going to Ada way. It will be useful to revisit the ca. 90 casts to [u]intptr_t that we have in gnulib when the shape of the new language will become clearer. Maybe it will have sizeof (type *) == 3 * sizeof (void *), who knows? For now, given that the MPX stuff is considered experimental, I think it's too early to rewrite code for its sake. Bruno
