+Subject: PATCH fix core dump if --enable-systemd
+
+From gnulib upstream commits:
+* 1e6a26f9312bb47e070f94b17b14dc1a6ffbb74f ("readutmp: fix core dump if --enable-systemd")
+Problem reported by Thorsten Kukuk <https://bugs.gnu.org/65617>.
+lib/readutmp.c (read_utmp_from_systemd):
+Don’t assume session_ptr != NULL if num_sessions == 0.
+In practice it can be null, and the man page OKs this behavior.
+
+* 3af1d7b0ce3a8e3ae565e7cea10cee6fd7cb8109 ("readutmp: Fix memory leak introduced by last commit.")
+lib/readutmp.c (read_utmp_from_systemd): If num_sessions == 0 and
+sessions != NULL, do call free (sessions).
