+From eaf9da8b5f8349c51cfc89dd8e39a1a61f89790a Mon Sep 17 00:00:00 2001

+Subject: [PATCH] gnulib/argp-help: Fix dereference of a possibly NULL state
+
+All other instances of call to __argp_failure() where there is
+a dgettext() call is first checking whether state is NULL before
+attempting to dereference it to get the root_argp->argp_domain.
