FYI, we noticed the following commit (built with gcc-7):

commit: 8edf8850d51e911a35b5d7aad4f8604db11abc66 ("perf machine: Use cached 
rbtrees")
url: 
https://github.com/0day-ci/linux/commits/Davidlohr-Bueso/tools-perf-Update-rbtree-implementation-and-optimize-users/20171128-120320



in testcase: perf-sanity-tests
with following parameters:




on test machine: qemu-system-x86_64 -enable-kvm -cpu kvm64,+ssse3 -smp 2 -m 8G

To reproduce:

        git clone https://github.com/intel/lkp-tests.git
        cd lkp-tests
        bin/lkp qemu -k <bzImage> job-script  # job-script is attached in this 
email



Thanks,
