double xj = gsl_vector_get (x, j);

This is, of course mathematically correct.
Nevertheless, the behavior is less than ideal

Shouldn't the GSL free-routines be changed like the following patch?
My thinking on that was that for most people calling the free()

Hello,
Is it possible to set the maximum step size in the ode (ordinary
differential equation) solvers? It's pretty important that the solver
doesn't start running away... Also, I will have large and sudden changes
in some of the parameters and I think I will need to reset the step size
to
