There are certainly much fewer moving parts in PostgreSQL code for
that one as this failure doesn't seem to rely on anything stored in
any tables or the catalogues.
I'd have thought it would be unlikely to be a compiler bug as wouldn't
that mean it'd fail every time?
Are there any Prime95-like stress testers for ARM that could be run on
this machine?
It would be good to kick this one out the pool if there's hardware issues.
