Hmph. I tried two more builds:
* downgraded llvm to llvm-9, compiled PG 12 from source
* installed postgresql-12.10-1.pgdg20.04+1 from pgdg repo
Neither of those configurations fail for me, so either
it's been fixed since 12.9, or (more likely) there is
something to your test case beyond what you've mentioned.
(I guess a long-shot possibility is that my raspberry pi 3B+
is sufficiently different hardware from your box as to not
see the problem. Doubt that though.)
Can you create a self-contained test case?
