OK, got it (my fault, as always, put the LimitCORE in the wrong line).
Here is the stack trace:
If you want to get rid of those "??" stack trace elements, you'll need
to install debug symbols for the xapian library. It depends on your
system how to do that (usually some separate package).

Difficult to figure out without a coredump + gdb
I have also battled quite a lot to make sure dovecot can core dump on
my Archlinux servers.
I remember that the key point was putting*fs.suid_dumpable=2* in
/etc/sysctl.d/ conf files, *LimitCORE=infinity*
in /etc/systemd/system/multi-user.target.wants/dovecot.service, and
rebooting the server.
My own coredumps are on /var/lib/systemd/coredump/
