Follow-up Comment #1, bug #49734 (project octave):

Does anyone else reproduce this? It has to be a script that is executed and
not copy-pasted. I get a position of 0 with both Octave 4.2 and with the
latest dev version.

I didn't noticed this before as 4.2 treats a zero position as if none was
specified (and the menu is put at the last position):

++
figure
uimenu('label','menu1','position',0)
--

Octave 4.3+ (rightfully) complains about it:

++
error: set: "position" must be greater than 0
error: called from
    uimenu at line 87 column 7
--

(Matlab displays a warning "Warning: Invalid uimenu position - not
rendering").

I wonder if the change that now triggers the error is related to the fix in
bug #48255. That said, the issue is that the following should never return 0:

++
close all
get(uimenu,'position')
--
