This example shows that something has recently broken in the implementation of lazy products with row-major matrices
typedef Eigen::Matrix<float, Eigen::Dynamic, Eigen::Dynamic, Eigen::RowMajor> Matrix;
Matrix A1(Matrix::Identity(2, 2));
Matrix A2(2, 1); A2 << 2, 3;
Matrix A3(2, 1);
A3.noalias() = A1 * A2; // Yields [2 2]' Wrong!
A3 = A1 * A2; // Yields [2 3]' OK!
This was working OK 1-2 weeks ago.
