This might be better off on freebsd-current, rather than hackers.

I can't answer your question but I have a number of questions for you:
0) What is the exact version of -current that you're running?
1) Can you share more details on "fails to build".  Are you in a position
   to share a build log.
2) Are you using ECC RAM?  Have you run memtest86 or similar?
3) Have you tried (eg) FreeBSD-13 instead of -current?

I presume that means a previous kernel/world could build/install world.
4) Have you tried a buildworld with your problematic install?

Any CPU-specific tweaks would be in the kernel.

(FTR, I have an AMD 5600X that's happily/stably running 13-stable).
