Hello there,

Got a server powered by "AlmaLinux 9.7 (Moss Jungle Cat)" with Dovecot 2.4.2 compiled from sources by directadmin with the following options:

./configure
--with-ldap=yes
--with-pam=yes
--prefix=/usr
--sysconfdir=/etc
--localstatedir=/var
--without-icu

Dovecot crashes and no IMAP auth is possible on the server

Got this only from dumped core:

Have no issue with Dovecot 2.4.1

Kindly advice.
