Things like malloc_usable_size() exist but you're not supposed to use the overage it tells you about so they're not very useful APIs.

This can be instrumented by the compiler or more likely runtime to detect buffer overruns. Imperfectly of course if you share the page(s) with other allocations but it's worth considering.
