Yes, and it applies to svd() too (and the previous fix for NaNs was applied to eigen but not to La.eigen).
I think this should be an error (with Inf or NaN): it was in the days of LIN/EISPACK-based code, and I don't understand why it has been chnaged to returning NAs in the case of NaN inputs. Now all of eigen, La.eigen, svd and La.svd give an error on matrix(Inf,2,2).
