Update of bug #63303 (project octave):

                 Release:                     dev => 7.2.0

Follow-up Comment #2:

Thanks for the report.

It looks like `dim_vector::redim` is used discarding the result.
Does the following change fix it for you?

   R *rvec = r.fortran_vec ();


It's probably too late for Octave 7.3. But it'd probably be worth to fix on
stable anyway.
