> The eal-intr-thread is not closed before memory cleanup in the process of exiting. There is a small probability that when the eal-intr-thread is about to use some pointers, the memory were just cleaned, which cause the > segment fault error caught by ASan.

> This patch close the eal-intr-thread before memory cleanup when exiting to avoid segment fault. And add some atomic operations to avoid executing rte_eal_cleanup in the child process spawned by fork() in some test > cases, e.g. debug_autotest of dpdk-test.
