Hi All,

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

Following the below page as ref= erence

https://doc.dpdk.org/guides/prog_guide/asan.h= tml

 

after compiling the dpdk with o= ptions “meson setup -Dbuildtype=3Ddebug  -Db_sanitize=3Daddress -Dexamp= les=3Dhelloworld build”

 =

program getting aborted can = anyone help me on this why I am unable to use ASAN with helloworld sample.<= o:p>
