I passed the literal "--socket-mem=2048,2048" in the array provided to rte_eal_init() function, where DPDK EAL tries to tokenize in place the string and it crashes trying to modify a readonly memory.  I don't know why DPDK does this.  But now I know, and I now see four rtemap_x files created for two sockets.

The function rte_eal_init() expects arguments to be like the arguments passed to main().
Those arguments are not read-only. You need to use strdup (or strdupa) to make mutable versions.
