A change set has been pushed to the development head, including
the change to use memmove(), which POSIX wants us to use, as well
as an additional test case in the script 'tests/syslogd.sh'.

It is unfortunate that I am unable to reproduce the issue with
either of Debian GNU/Linux, FreeBSD 10 and OpenIndiana; all the
more so, since the report of Alex Kost in 'guix-devel' clearly
demonstrates all details to be seen in an actual failure. I for
one would be interested in more detail, so as to be able to
identify some system characteristics, making the corresponding
libc implementation prone to be sensitive to issued with over-
lapping string buffers.

Thank your for bringing the issue forward to us.
