Update of bug #58686 (project octave):

                  Status:                   Fixed => In Progress            
             Open/Closed:                  Closed => Open

Follow-up Comment #8:

This change probably broke some tests on the no-extras buildbots.
The first one is:

>>>>> processing
/scratch/buildbot/workers/jwe-debian-x86_64-2/stable-no-extras-debian/src/test/publish/publish.tst
***** test
 visibility = get (0, "defaultfigurevisible");
 toolkit = graphics_toolkit ();
 unwind_protect
   if (! __have_feature__ ("QT_OFFSCREEN")
       || ! strcmp (graphics_toolkit (), "qt"))
     try
       graphics_toolkit ("gnuplot");
     catch
       ## The system doesn't support gnuplot for drawing hidden
       ## figures.  Just return and have test marked as passing.
       return;
     end_try_catch
   endif
   set (0, "defaultfigurevisible", "off");
   scripts = dir ("test_script*.m");
   tmpDir = tempname ();
   mkdir (tmpDir);
   opts.outputDir = tmpDir;
   for fname = {scripts.name}
     publish (fname{1}, opts);
   endfor
   confirm_recursive_rmdir (false, "local");
   rmdir (tmpDir, "s");
 unwind_protect_cleanup
   set (0, "defaultfigurevisible", visibility);
   graphics_toolkit (toolkit);
 end_unwind_protect
!!!!! test failed
Element 1 in argument list is not defined


Easier steps to reproduce the same error are:

a = struct ("b", {});
{a.b}


The same works in Matlab R2020a without error:

>> a = struct('b', {})
a = 
  0×0 empty struct array with fields:
    b
>> {a.b}
ans =
  0×0 empty cell array
