LGTM, but your commit message should be more descriptive than your current summary. Something like:

Ensure that the vptr store in the most-derived constructor is not behind an invariant group barrier. Previously, the base-most vptr store would be the one behind no barrier, and that could result in the creator of the object thinking it had the base-most vtable.
