Merging r340823:

------------------------------------------------------------------------
r340823 | marshall | 2018-08-28 15:29:30 +0200 (Tue, 28 Aug 2018) | 1 line

Use addressof instead of operator& in make_shared. Fixes PR38729. As a drive-by, make the same change in raw_storage_iterator (twice).
