Segmentation fault occurs when aggregate bandwidth logging is enabled (--bandwidth-log) and numjobs is an even multiple of 8. Fault occurs because logic is using the terminating value of struct thread_data *td from the most recent for_each_td(). This bug was caught by the refactoring of for_each_td().
