Follow-up Comment #13, bug #48186 (project octave):

I think this report should be reopened. While the code from comment #5 runs
fine with 5.1, it returns an error with current dev:

octave:1> F = figure('Units','normalized');
octave:2> uipanel(F,'Position',[0 0 0.45 1],
octave:3> uipanel(F,'Position',[0.55 0 0.45 1]);
octave:4> close(F)
error: delete: first argument must be a filename or graphics handle
error: called from
    delete at line 61 column 5
    delete at line 58 column 5
    closereq at line 37 column 5
    close at line 112 column 5

and if you revert the order the two uipanels are created then Octave seems to
be stuck in an infinite loop:

octave:1> F = figure('Units','normalized');
octave:2> uipanel(F,'Position',[0.55 0 0.45 1]);
octave:3> uipanel(F,'Position',[0 0 0.45 1],
octave:4> close(F)
