[Help-gsl] bug in gsl_odeiv_evolve_apply ?

I am getting

int status = gsl_odeiv_evolve_apply(ODEEvolver, ODEController,
ODEStepper, &ODESystem, &t, ti, &h, &y);

to return with y = GSL_NAN, but status = 0.
This occurs for too large initial h, in other words
choosing the initial h small enough makes the function return
the proper y.
Should that be reported as a bug, or is it ok not to converge (what I
believe is happening) and return no error code ?
