+Subject: [PATCH] output: Avoid tickling UBSAN with memcpy(dest, NULL, 0)
+
+Even though all libc handle it sanely (because size 0 says there is
+nothing to copy), NULL is not a valid source pointer per a strict
+reading of C, so UBSAN flags it:
+
++output.c:511:9: runtime error: null pointer passed as argument 2, which is declared to never be null
+
+* src/output.c (make_room_for): Skip no-op memcpy.
+Fixes: https://savannah.gnu.org/support/index.php?110809
