Follow-up Comment #3, bug #53991 (project octave):
I think the problem is in the algorithm itself. Matlab returns with the exit
flag -2 which means
Converged to a point that is not a root.
This happens when the Jacobian fjac has a small norm (0, in this report) but
the solution fvec is far from 0. This can be detected before calling
__dogleg__ at line 307.
