What version of head ( -r?????? )?

Is this an AMD Ryzen, AMD Ryzen Threadripper, or AMD Epyc
context? If not, what is the alternative in use? Other
details could be relevant as well.

There was a time when there were various reports of such
for Ryzen variants but the failure would not be on the
same file each time and some builds would work. (I've
seen such myself but likely will not have access to a
Ryzen context again and it will likely be months for
access to a Ryzen Threadripper. So I'm just suggesting
additional information to report.)
