How do I fix gsl: evolve.c:317: ERROR: step dimension must match evolution size

[Bo Johnson]

I'm writing a class to generalize solving differential equations. 
However, I'm getting an error I don't think should be happening. My 
class looks as follows

   
|classDynSys{public:DynSys(constsize_tsize,doublestartTime,doubleendTime,doublestepSize,double*iState,int(*func)(double,constdouble*,double*,void*),int(*jac)(double,constdouble*,double*,double*,void*),constgsl_odeiv2_step_type*T
   
=gsl_odeiv2_step_rk8pd):T(T),size(size),t(startTime),t1(endTime),h(stepSize){y
   =newdouble[size];y =iState;yPrev =newdouble[size];s
   =gsl_odeiv2_step_alloc(T,size);c
   =gsl_odeiv2_control_y_new(1e-6,0.0);e
   =gsl_odeiv2_evolve_alloc(size);sys
   
={func,jac,size,0};}~DynSys(){delete[]y;delete[]yPrev;gsl_odeiv2_evolve_free(e);gsl_odeiv2_control_free(c);gsl_odeiv2_step_free(s);}voidstep(){printf("e
   dim: %ld\n",e->dimension);printf("s dim:
   %ld\n",s->dimension);printf("y: %.5f %.5f %.5f %.5f %.5f
   %.5f\n",y[0],y[1],y[2],y[3],y[4],y[5]);tPrev =t;yPrev
   =std::copy(y,y+size,yPrev);intstatus
   =gsl_odeiv2_evolve_apply_fixed_step(e,c,s,&sys,&t,h,y);if(status
   !=GSL_SUCCESS){printf("Error:
   
%s\n",gsl_strerror(status));throwstd::logic_error(gsl_strerror(status));}}doublegetT(){returnt;}voidsetY(double*y){y
   
=y;}private:constgsl_odeiv2_step_type*T;gsl_odeiv2_step*s;gsl_odeiv2_control*c;gsl_odeiv2_evolve*e;gsl_odeiv2_system
   
sys;constsize_tsize;doublet;doublet1;doubleh;double*y;doubletPrev;double*yPrev;};

||And in my test code for stepping

   
|intmain(){doublestate[]={1.0,0.0,0.0,0.796975,0.11637,0.0185312};constsize_tsize
   =6;DynSyssystem(size,0.0,40.0,1e-3,state,func,jac);system.step();printf("t:
   %.5f\n",system.getT());system.step();printf("t:
   %.5f\n",system.getT());return0;}|

I get the error that the "step dimension must match the evolution size." 
But based on my initialization and the output of the code when run, the 
step dimension matches the evolution size. Any help on understanding 
what's happening is appreciated.
