Heap corruption, not good. How often does this happen?

It says it dumped core file, so it did write it somewhere. You just
might not be finding it.

auth-workers are chdired to Dovecot's base_dir (e.g. /var/run/dovecot).
The core file is normally written there, do you see it? Try removing
path from core_pattern and see if it shows up there then?
