9030,Should pass steppers by reference in integrate functions,anikin@…,karsten,"The ''integrate'' family of functions takes steppers by value, but steppers like the most useful '''runge_kutta_dopri5''' may contain state which is not the best type to copy around. The worst happens if you try to use SSE-aligned vector for state type, e.g. Eigen::Array. Passing aligned struct by value cannot preserve the alignment and the program crashes. Which makes it impossible to use SSE vectorization with odeint. I think you need to change to passing steppers by reference or add odeint::unwrap_reference< Stepper > wherever steppers are passed, so that boost::ref could be used with them.",Feature Requests,closed,To Be Determined,odeint,Boost 1.54.0,Showstopper,fixed,st,
