I also have this kind of segfault since the update :

Is this easy to reproduce? Can you try with valgrind? It will slow down the logins a bit though.
service auth-worker { executable = /usr/bin/valgrind -q --vgdb=no /usr/lib/dovecot/auth -w }
At least one good thing about this crash is that it seems to happen only at deinit, so it's not impacting users.
