I've seen the build coordinator on bayfront crash a couple of times, and
it seems to be segfaulting, maybe in gnutls?

Did you manage to get a backtrace?

We didn’t experience segfaults in Guile-GnuTLS in recent years but it’s
never too late…

Not yet, I've been trying to change the core file size limit with the
prlimit command, but I haven't seen any core dump files yet, so I'm not
sure if I've missed something.

I've finally managed to get core dumps working for this now, and I've
reported the problem upstream.
