[eigen] Error when using tridiagonalization_inplace_selector

[Alberto Luaces]

Hi, I have found a build error in openmvg when using 3.4.0, shown with this 
snippet.  Do you think it is a bug in Eigen?

Thanks!

#include <Eigen/Dense>

int main(){
    using MatX9 = Eigen::Matrix<double, -1, 9>;
    MatX9 epipolar_constraint(7, 9);
    epipolar_constraint.fill(0.0);
    // EncodeEpipolarEquation(x1, x2, &epipolar_constraint);                    
                                                                                
                             
    Eigen::SelfAdjointEigenSolver<MatX9> solver
        (epipolar_constraint.transpose() * epipolar_constraint);
    return 0;
}
