Confirm make check failure reason

Hi all, I'm trying to use AVX2 to accelerate base64 encode/decode. "make check" could pass in my local host development. There's unknown failure in Ceph community's verification environment. I can't find why the failure is triggered and how to reproduce it. Could anyone help check the failure log to give some clue about how to reproduce it? 1) PR: https://github.com/ceph/ceph/pull/35080 2) Error log: https://jenkins.ceph.com/job/ceph-pull-requests/51749/ B.R.
