I am building an app based on dpdk-stable-18.11.8. I am seeing a
segmentation fault in my call to rte_eth_rx_burst(). I ran gdb on the core
dump and I see:

#0  0x0000000000f65680 in rte_eth_devices ()
#1  0x000000000048a03a in rte_eth_rx_burst (nb_pkts=7,
rx_pkts=0x7fab40620480, queue_id=0, port_id=<optimized out>)
#2  Socket_poll (ucRxPortId=<optimized out>, ucRxQueId=ucRxQueId@entry=0
'\000', uiMaxNumOfRxFrm=uiMaxNumOfRxFrm@entry=7,
    pISocketListener=pISocketListener@entry=0xf635d0 <FH_gtFrontHaulObj+16>)

#6  0x00007fab4172388d in clone () from /lib64/libc.so.6

So it seems that rte_eth_rx_burst() calls  rte_eth_devices () and that
function crashes, presumably because of an illegal memory access.

Please can anyone suggest a way of debugging this further to determine the
