Already fixed in the last 8.22 release:
http://git.sv.gnu.org/gitweb/?p=coreutils.git;a=commit;h=e52293aa

You might want to log a bug with your distro to backport the fix?

thanks,

We prefer plain text.  Spending 105 kb on a png when a transcript of
your console session would occupy less than 1 kb is a waste of bandwidth.

At any rate, I tried and failed to reproduce your setup:

$ cd /tmp/
$ mkdir -p aaa/aaa1 bbb
$ cd aaa
$ ln -fnrsv aaa1 ../bbb/
‘../bbb/aaa1’ -> ‘../aaa/aaa1’
$ ln -fnrsv aaa1 ../bbb/
‘../bbb/aaa1’ -> ‘../aaa/aaa1’


Using 'tree(1)' to display your directory does not necessarily provide
enough information (although it did mention that it listed 3
directories, so I'm assuming aaa1 is an empty directory - but that's
what I used above in my reproduction attempt).  Could you instead please
show 'ls -lR aaa bbb' before your 'cd aaa' step, so we have a more
complete picture of your starting setup?

Also, it would help if you explained what you thought was odd - your
graphic kind of hints at that, by how it shows the same command executed
twice with different outputs, but you could have provided more details.
