Hello 
I am tring to run dpdk example with asan.
I have compile dpdk and example as directed by link https://github.com/DPDK/dpdk/blob/v21.11/doc/guides/prog_guide/asan.rst
But I always get result as follow:
=================================================================
==20078== ERROR: AddressSanitizer: SEGV on unknown address 0x000000000000 (pc 0x000000d28b92 sp 0x7ffc6a983b90 bp 0x7ffc6a983bb0 T0)

==20078== ABORTING

It's not same as what i see in asan.rst<https://github.com/DPDK/dpdk/blob/v21.11/doc/guides/prog_guide/asan.rst>.This result doesn't look right. 
My env:
Gcc :9.3.0
Libasan: 4.8.5
Looking forward to hearing from you
