segfaults with cyrus-imapd 3.0.9 on latest arch linux

[Andreas Piesk]

Hello list,

i'm trying to get cyrus-imapd 3.0.9 (testet 3.0.8 too) running on latest arch linux. Here's the configure summary:

The software builds succesful but executing commands with cyradm produces core dumps like this one:

looks like the imapd stack trace. the mailbox file seems to be fine:

# file /var/lib/cyrus/mailboxes.db
/var/lib/cyrus/mailboxes.db: Cyrus twoskip DB

# cyr_dbtool /var/lib/cyrus/mailboxes.db twoskip consistent
Yes, consistent

and has an entry for user.test:

# cyr_dbtool /var/lib/cyrus/mailboxes.db twoskip dump

I looked at permissions but both imapd and cyrdump open the mailbox file sucessfully in r/w mode. I use the configs from /doc/examples/*/normal.conf.

I'm lost. Any hints?

Best Regards,
