Hey,
i am now a bit deeper into dovecot debugging with gdb and have a full bt now, with debugging infos.
Is there a patch that resolve this Problem in dovecot 2.2.22-1ubuntu2.13 for ubuntu 16?
Here the bt:

Betreff: doveadm search segfault Dovecot 2.2.22
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
