I could not reproduce that from scratch for now either since if I recalled that
correctly, I reproduce that on one specific Sky Lake machine, not all.

BTW, the DSB issue is some time just a "bad luck" caused by code layout,
especially on old Intel platforms.

Let me try to find where my regression binary to sort out that.
