kernel test robot Wed, 04 Jul 2018 00:03:51 -0700

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

commit: 32a4debc7c89ee5e29c0bbdfdd3ae0ce0e01057f ("[PATCH] perf tests: Fix 
regex for record+probe_libc_inet_pton.sh")
url: 
https://github.com/0day-ci/linux/commits/Sandipan-Das/perf-tests-Fix-regex-for-record-probe_libc_inet_pton-sh/20180521-130408



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

        perf_compiler: gcc



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

log/backtrace):


2018-05-22 17:41:14 sudo 
/usr/src/linux-perf-x86_64-fedora-25-32a4debc7c89ee5e29c0bbdfdd3ae0ce0e01057f/tools/perf/perf

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,
