[Octave-bug-tracker] [bug #58686] Interpreter silently ignores inputs

[Kai Torben Ohlhus]

Follow-up Comment #4, bug #58686 (project octave):

Thank you for looking into this Rik 🙂

Matlab R2020b gives an error for calling the function in comment #0.


>> assert (do_nothing (4), rand (3))
Output argument "retval" (and maybe others) not assigned
during call to "do_nothing".


The proposed suggestion of comment #0 can only detect that some
octave_value_list (ovl) element was not properly assigned, because we are
already inside the called function.

The desired solution is, that during the creation of that ovl an error with
nice message is thrown.

Workarounds with empty elements, I suspect to be the root of new
inconsistencies.
