Hello
I reported a bug in PCA component in Feb. In CGAL 3.5 beta1 I have seen the change, but I don't think the problem is fixed.
It is about line 709-710 in PCA_util.h of CGAL 3.4. The condition is too strong for regular case. Now in CGAL 3.5 beta1, it is line 708-709. I think the condition is still too strong, but for degenerate case. To confirm degenerate case, only "eigen_values[1] == eigen_values[2]" is needed. "eigen_values[0] != eigen_values[2]" is not a guarantee of regular case.
