In a few cases we call BUG() in a fault case and a core file will be
generated.
For example:
        if (fault_injected(FI_DUMP_EARLY)) {
                pr_info("fault: CRIU sudden detach\n");
                BUG();
        }

We don't check exit codes of tests processes, because they are
daemonized. So the answer is yes.
