doveadm search segfault Dovecot 2.2.22

Thu Sep 17 18:28:05 EEST 2020

Good Evening,

i have a serius problem by usung the search function via imap or via
doveadm.

If i run this command:

doveadm search -u <user> mailbox INBOX text 'Hello'

I receive this line in my maillog:

dovecot: imap(<user>): Fatal: master: service(imap): child 7472 killed with
signal 11 (core dumped)

in my /var/log/apport.log i can see this:

ERROR: apport (pid 17785) Thu Sep 17 17:19:01 2020: called for pid 17777,
signal 11, core limit 0, dump mode 1

What surprises me is that this problem only occurs with a text search in the
inbox, I search in other mailboxes or only in the header this problem does
not occur.

Can anyone give me a tip on how I can solve this problem without upgrading
to 2.33?

Mit freundlichen Grüßen

Yours sincerely
