I have downloaded, compiled and installed the latest Octave-11.1.0 release
tar-ball onto my laptop with Ubuntu 24.04.

When running the test suite, I get one failing unit test, that can sometimes
be reproduced also on its own:


octave:11> test dir.m
***** test
 orig_dir = pwd ();
 tmp_dir = tempname ();
 unwind_protect
   assert (mkdir (tmp_dir));
   chdir (tmp_dir);
   fclose (fopen ("f1", "w"));
   list = dir ();
   assert (isstruct (list) && ! isempty (list));
   assert (fieldnames (list),
           {"name"; "folder"; "date"; "bytes"; "isdir"; "datenum";
"statinfo"});

   if (isunix ())
     idx = find (strcmp ({list.name}, "."), 1);
     assert ({list(idx:idx+1).name}, {".", ".."});
     assert ([list(idx:idx+1).isdir], [true true]);
   endif

   ## test that specifying a filename works the same as using a directory.
   found = find (! [list.isdir], 1);
   if (! isempty (found))
     list2 = dir (fullfile (list(found).folder, list(found).name));
     assert (list(found), list2);
   endif
 unwind_protect_cleanup
   chdir (orig_dir);
   confirm_recursive_rmdir (false, "local");
   if (exist (tmp_dir))
     sts = rmdir (tmp_dir, "s");
   endif
 end_unwind_protect
!!!!! test failed
ASSERT errors for:  assert (cond {i},expected {i},tol)

  Location  |  Observed  |  Expected  |  Reason
     ()      1771970719.5172 1771970719.5212   Abs err 0.0039999 exceeds tol 0
by 0.004
octave:12>


When doing "test dir.m" ten times on my laptop, I can most of the time see
this failing unit test once.

Let me know if you need more information on my system, or any other details.
