First,
Thank you for taking the time to report the problem.

Technically,
This is not a bug in "sed", but in a common library we use called 
"gnulib". It could still be a bug, or perhaps a problem specific to your 
environment - but it isn't directly related to sed.

As Eric wrote,
We need few more details.

1.
Is this reproducible?
After running "make check", there should be an executable file called 
"gnulib-tests/test-symlink".
If you run it directly, do you still get an error?

If you don't get an error when running it directly,
do you still see an error when running "make check" ?


2.
What is the operating system, and the file system you are using?
The output of the following commands would help to diagnose the issue:

    uname -a
    lsb_release -a
    stat -f .
    df -h --output .

sed deals with symlinks directly only when the
    "--in-place --follow-symlinks"
options are used together.
sed also includes a specific "follow-symlink" test and it didn't fail on 
your system.

In practice, like Eric wrote, this failure should not affect you under
typical sed usage.


As such, I'm closing this bug report, but discussion can continue by
replying to this thread. If this ends up being a problem in gnulib,
we can forward it to bug-gnulib <at> gnu.org .
