Hello, Users.
Here is way to crash subversion 1.8.0 release on FreeBSD -- try to
update WC which is symlink to real WC. It worked in 1.7.x. Repository
and access scheme and repo's content doesn't matter, "serf" repo is
used for illustration, but it crashes with any repo and any scheme
(https, svn, etc).
