Comment 1 Jim Meyering 2007-05-16 12:41:00 UTC 
Thanks for the report.
This was fixed upstream, but is not in a stable release:

NEWS:
  ls -x DIR would sometimes output the wrong string in place of the
  first entry.  [introduced in coreutils-6.8]

Here's the upstream fix:

Better fix?

Yeah, that's the one.  Does the upstream fix work when there is nothing to
list? It looks like sorted_file[0] would be some random pointer in that case.
FWIW this is the fix I came up with (based on what's in F7, not upstream).
Comment 3 Jim Meyering 2007-05-16 13:26:27 UTC 
Hi Gary,
Good point: that patch is a little fragile.  However, it does appear to work
even  in that case, since when there are no entries to list, cwd_n_used is 0, in
which case print_horizontal cannot be called.  But if you find a way to make ls
misbehave, please let me know.
Comment 4 Gary Benson 2007-05-16 13:49:10 UTC 
Ah, that would explain it.
