woodlouse just showed a failure that looked a bit familiar:
https://buildfarm.postgresql.org/cgi-bin/show_log.pl?nm=woodlouse&dt=2018-04-17%2016%3A42%3A43
I trawled the buildfarm logs for similar failures, and there are several:

The test case that's failing, in identity.sql, has been there since
early February; the lack of any crashes till more recently suggests
that something committed in mid-to-late March broke it.
I have no idea what's going on there, but I think this is clearly
something we need to consider an open item for PG11. I'll put it
on the list.
