That's interesting, but it doesn't make sense to me.  DPDK #defines RTE_CPU_AND directly to CPU_AND on Linux, and CPU_AND is provided by system sched.h.  Are you able to get the exact instruction that this crashes on via gdb?  Not just the instruction, but also the values of whatever registers used by that instruction.  Your original e-mail indicated "illegal operand" in the log, so that's a little bit of clue.

    Hi Jim,

    Thanks will try out your suggestions. 

    Before that, I wanted to update you, on the only time I was able to hit this issue without the -g option, it was crashing in the following macro inside the compute_ctrl_threads_cpuset line 1466.

    (eal_adjust_config -> compute_ctrl_threads_cpuset) 
    In compute_ctrl_threads_cpuset , line 1466
    1466         RTE_CPU_AND(cpuset, cpuset, &default_set);
