The CPU on this machine is: "Intel(R) Core(TM) i7-3770 CPU @ 3.40GHz (fam: 06, model: 3a, stepping: 09)" running with "3.10.0-862.el7.x86_64". Our builds are running fine on newest hardware, nevertheless the segfault seems a bit weird even for an unsupported CPU (some error prompt would be more friendly), any suggestion on what the problem might be?
