Bug scenario: 1. start testpmd: $ dpdk-testpmd -l 4-6 -a 0000:7d:00.0 --trace=.* -- -i 2. quit testpmd and then observed segment fault: Bye... Segmentation fault (core dumped) The root cause is that rte_trace_save() and eal_trace_fini() access the huge pages which were cleanup by rte_eal_memory_detach(). This patch moves rte_trace_save() and eal_trace_fini() before rte_eal_memory_detach() to fix the bug.
