It looks as though this error message is associated with the way you are using 'new' rather than being about 'new' itself. Are you using Simulink? If I were you, I would read that message very carefully and see if it contains a clue as what the trouble is. It seems to hint that some iteration you have set up, presumably involving 'new', is not converging properly.
