We are able to compile and run the pipeline. However, we observed a lot of pkts not executing the acl lookup properly. While debugging, we found that a lot of pkts were missed in packets out mask. This aspect was checked with the rte_table_acl_lookup function in lib/librte_table/rte_table_acl.c file. Clang 5 is from September 2017 Leading edge Linux distributions are using Clang 14 from March 2022 Current release is Clang 16. Does your problem reproduce on current compiler? Or if built with Gcc
