Public bug reported: It seems that (in my Ubuntu Jaunty) running "iostat -d -k -N -x -n 1" triggers the stack smashing protection:

The statistics reported by sar concern I/O transfer rates, paging activity, process-related activities, interrupts, network activity, memory and swap space utilization, CPU utilization, kernel activities and TTY statistics, among others. Both UP and SMP machines are fully supported.
