Hi All,

  I am trying to run dpdk helloworld example with ASAN tool to check the memory leak.

Following the below page as reference

https://doc.dpdk.org/guides/prog_guide/asan.html

after compiling the dpdk with options “meson setup -Dbuildtype=debug  -Db_sanitize=address -Dexamples=helloworld build”

program getting aborted can anyone help me on this why I am unable to use ASAN with helloworld sample.

Snipped of  the error :

./build/examples/dpdk-helloworld -l 0-3 -n 4

EAL: Detected 72 lcore(s)

EAL: Detected 2 NUMA nodes

EAL: WARNING! Base virtual address hint (0x100005000 != 0x7f2a56500000) not respected!

EAL:    This may cause issues with mapping memory into secondary processes

EAL: Multi-process socket /var/run/dpdk/rte/mp_socket
