Yes I realize they are problems outside of rxe but I didn't run into
any crashes when I ran rpring on the 5.14-rc1 (it was hanging and
that's what I reported here) so I thought perhaps later patches have
addressed the crashes I've seen.

Would you like me to post a separate email report on the crash(es) (I
don't recall if it's the same one or two different ones)?
