I'm using Dovecot 1.1.15 on OpenBSD 4.4. How can I debug this?

# /usr/local/sbin/dovecot --exec-mail ext /usr/local/libexec/dovecot/expire- tool Segmentation fault (core dumped) # gdb /usr/local/sbin/dovecot (gdb) run --exec-mail ext /usr/local/libexec/dovecot/expire-tool

This won't really work. Instead when you ran the expire-tool, it said it dumped core, so run:

gdb /usr/local/libexec/dovecot/expire-tool core bt full Okay thanks:)

So:

Okay thanks:)

So:

#2 0x1c002482 in auth_parse_input (conn=0x7fd98140, args=0x81a1f01e "leva\tuid=xxxx\tgid=xxxx\thome=/maildirhome/leva\tquota_rule=*:storage=0 \tquota_rule2=Trash:storage=0") at auth-client.c:142

Looks like I broke it in 1.1.15. This should fix it: http://hg.dovecot.org/dovecot-1.1/rev/18c2e4ee94eb

Thanks, top notch support, as always :)

Daniel
