在 dpdk 示例应用程序（示例：dpdk-testpmd）中使用 valgrind 时，它会在启动时卡住，如下所示：
[root@node1 app]# valgrind --leak-check=yes ./dpdk-testpmd -a 0000:af:00.3

看来我需要在 valgrind 源代码中放置一个 gdb 并进行分析。然而，在这样做之前，我想检查一下是否有人遇到过类似的问题并找到了解决方案。
请注意，我的意图不是调试内存泄漏/由 rte_* 调用分配/管理的内存区域的损坏。相反，我希望使用 valgrind 调试应用程序使用常规 malloc 调用分配的内存区域中的泄漏/损坏。此应用程序链接到 dpdk 库。
