[ shrug... ] It's not impossible that you've got two lemons ... stranger
things have happened. One pretty obvious opportunity for a common-mode
failure is if you loaded them up with RAM chips from the same batch.
The symptoms shown in your crashreporter logs don't look anything like
a software problem to me: they're not consistent, and a lot of the
crashes are in code that is exercised exactly the same way on every
process start. Also, we're not seeing reports of similar problems from
anyone else running PG on Intel Mac; which is definitely a nonempty
population --- there's one in the buildfarm for instance, and it's
showing zero failures in the back branches:

So I'm going to stick to my bet that it's a hardware problem.
