If you are using systemd, create /etc/systemd/system/dovecot.service.d/limits.conf and put [Service]LimitCORE=infinity

Nope, I'm on a debian 7, without systemd. Anyway, I've resolved the issue: I had to set fs.suid_dumpable BEFORE starting dovecot.
I've got a core dump, and here is the backtrace. Let me know if you want the core file.
