+Subject: [PATCH] fix nullptr deref in archive
+
+Hardened toolchains (eg, mainline Fedora) no longer tolerate null
+derefs that were silently trapped/ignored in earlier versions.  This
+eliminates a nullptr deref in archive.hpp that was failing several
+unit tests (and causing crashes) when trying to manipulate
+default-constructed archive objects.
+
+Adapted original patch according the comment in the PR.
