This is caused by the following two methods:

  /// Compute Jacobian matrix J (optional)
  virtual Matrix& Jmatrix(const uBlasVector& u, real t);

  /// Compute LHS matrix M (optional)
  virtual Matrix& Mmatrix(real t);

I don't recognize these two. Can we remove them and the stuff in
MonoAdaptiveJacobian::update()? It seems to be special purpose code
for cG(1)/dG(0).
