For proper alignment on the heap Eigen needs to have a custom allocator. There are two forms, new and in-place new. To make sure that memory is aligned using new, one needs to overload new by adding EIGEN_MAKE_ALIGNED_OPERATOR_NEW to any struct which contains a fixed size Eigen type either through inheritance or as a direct or indirect member. For the in-place new one need to use the Eigen::aligned_allocator (e.g. for std::vector, std::list, FixedArray, etc.). For more details see: https://eigen.tuxfamily.org/dox/group__DenseMatrixManipulation__Alignement.html This CL adds EIGEN_MAKE_ALIGNED_OPERATOR_NEW to all structs, which contain fixed-size Eigen types and uses the Eigen::aligned_allocator for containers which stores structs of fixed-size Eigen types.
