            The LU branch relates to the community releases and the master branch. It sounds like this suggestion is something that should be tracked on the SEA project (which it is)

            LU-7382 is a different issue. This one reproduces with LU-7382 patch applied but on 2.7 branch. master doesn't need it now.

            I agree with Dmitry - it's just a pointer.

            Ok. This means not affected versions more than v2.8.54.
            The u.normal.via_iter is just pointer. So, modification of it not affect the content.

            The assertion was hit before https://review.whamcloud.com/#/c/20256/  but u.normal.via_iter is still modified.
