CentOS7, Xeon(R) CPU E5-2660 v2 model (first released 2013)
Description
This fails with an invalid opcode exception when running on a Xeon(R) CPU E5-2660 v2 model (first released 2013), but works on a slightly more recent Xeon(R) CPU E5-2676 v3 from 2014.
One of the difference between the two models is that both support avx, but only the newer model also supports avx2 extensions.
Crashes already when trying to run "maxscale --version"
