No. That problem exists too, but is irrelevant for the current code base:
there has been one bug of that kind about three years ago, AFAIK that is

The problem that was addressed here was that, officially according to POSIX,
using realloc() on a buffer returned by posix_memalign() is an undefined
behaviour. In practice, we had quite a few of these cases but that never
caused any problem.
