Hi, Thank you for pointing me about -xc99 flag, I have compiled and installed dovecot inplace of version 1.0.5 without any special actions on the upgrade. And after starting it immediately got in it's log file messages like:
dovecot: Oct 16 23:10:18 Error: IMAP(seriv): file_set_size() failed with index cache file /var/spool/imap/seriv/.imap/.git-altlinux-ru/dovecot.index.cache: Invalid argument
I have tried to delete dovecot.index.cache files from imap directories, but this did not helped:

Then I have tried to delete all dovecot.index* files from there, but the messages in dovecot.log are almost the same:

One more problem is with fd limit: I have a small dovecot installation, so don't want to increase fd limit. I tried to decreasee max_mail_processes, login_max_processes_count and login_max_connections, but still I have
# /opt/dovecot/sbin/dovecot -n # 1.1.beta3: /opt/dovecot/etc/dovecot.conf Warning: fd limit 256 is lower than what Dovecot can use under full load (more than 384).

So I reverted to 1.0.5 which works fine for me.
