Here's one example

But in most cases it's good enough to allocate every area with malloc
and let valgrind do its thing. I'm not sure exactly what it does, but by
default there seems to be some red-zone around each malloc:ed area.

Annotations can be useful when playing with alignment, like in the
above example, or when an allocated area is explicitly off-limits. E.g.,
marking the area between _mp_size and _mp_alloc in our mpz objects.
