Follow-up Comment #2, bug #60738 (project octave):
The modification you made can still have the same issue but can be fixed by
changing the line
real_neg_eigv = (real (eigv) < 0) & (imag (eigv) == 0);
to allow a small tolerance
abs_imag_eigv = abs (imag (eigv));
real_neg_eigv = (real (eigv) < 0) & (abs_imag_eigv <= 10 * eps (max
(abs_imag_eigv))));
