Ok, it needs to be a little bit different:
template<typename Derived>
inline IsometryTransformType operator*(const
RotationBase<Derived,Dim>& r) const
{
IsometryTransformType res;
res.matrix().setZero();
res.linear() = r.toRotationMatrix().derived();
res.translation() = m_coeffs;
res.matrix().row(Dim).setZero();
res(Dim,Dim) = Scalar(1);
return res;
}
Here, it's working...
