Ah, understood, it is in the responsibility of the caller to avoid the memleak.
BTW may I ask you about your opinion about this warning of cppcheck in lib/flex_array.c:

        for (part_nr = start_part; part_nr <= end_part; part_nr++) {<--- Memory leak: part
                part = __fa_get_part(fa, part_nr, flags);
                if (!part)
                        return -ENOMEM;
        }
        return 0;
