As far as I understood the POSIX text, it is implementation-defined
behaviour and POSIX gives two valid implementation options. The patch
removed some code (less code is always good) and now we are in line
with
Linux and FreeBSD.
We should be more focused on correctness. We don't agree with not
checking null pointers as arguments either.
If the application uses the memory returned, there is no guarantee on
the size and this leads quite naturally to a buffer overflow.
I don't care that much if we return a unique pointer or NULL, but it
should be consistent across the directives.
