FYI, we noticed the following commit (built with gcc-11):

commit: a5202946dc7b20bf2abe1bd35adf2f46aa155ac0 ("KVM: selftests: Add a test to get/set triple fault event") https://git.kernel.org/cgit/virt/kvm/kvm.git lbr-for-weijiang

in testcase: kernel-selftests
version: kernel-selftests-x86_64-d889b151-1_20220608
with following parameters:

	group: kvm

To reproduce:

        git clone https://github.com/intel/lkp-tests.git
        cd lkp-tests
        sudo bin/lkp install job.yaml           # job file is attached in this email
        bin/lkp split-job --compatible job.yaml # generate the yaml file for lkp run
        sudo bin/lkp run generated-yaml-file

        # if come across any failure that blocks the test,
        # please remove ~/.lkp and /lkp dir to run from a clean state.
