--- Comment #2 from Ed Maste <emaste at freebsd.org> ---
In fact it's even worse; from filter_reloc():

        for(i = 0; (uint64_t)i < n; i++) {
                if (s->type == SHT_REL) {
                        if (gelf_getrel(id, i, &rel) != &rel)
                                errx(EXIT_FAILURE, "gelf_getrel failed: %s",
                                    elf_errmsg(-1));
                } else {
                        if (gelf_getrela(id, i, &rela) != &rela)
                                errx(EXIT_FAILURE, "gelf_getrel failed: %s",
                                    elf_errmsg(-1));
                }
                name = elf_strptr(ecp->ein, elf_ndxscn(ecp->strtab->is),
                    GELF_R_SYM(rel.r_info));

rel.r_info is uninitialized if s->type == SHT_RELA.
