Hi!
Can you provide gdb bt full output for this crash?
Install debug symbols (if necessary) and
gdb /usr/libexec/dovecot/imap /path/to/core bt full

We are pleased to release v2.3.17 of Dovecot.
Hello,
on my private fully updated Fedora 34 system I've replaced version 2.3.16 by version 2.3.17 without touching the configuration.
Whereas version 2.3.16 worked the new 2.3.17 says Oct 28 11:29:27 christo dovecot[216609]: imap-login: Login: frank, 127.0.0.1, TLS Oct 28 11:29:27 christo dovecot[216609]: IMAP(frank,127.0.0.1): ID sent: name=imapsync, version=1.977, os=linux, vendor=Gilles LAMIRAL, support-url=https://imapsync.lamiral.info/, date=23-Dec-2019 20:18:02 +0000, side=host2 Oct 28 11:29:27 christo dovecot[216609]: IMAP(frank,127.0.0.1): Fatal: master: service(imap): child 216943 killed with signal 11 (core dumped) Oct 28 11:29:27 christo dovecot[216609]: imap-login: Login: frank, 127.0.0.1, TLS Oct 28 11:29:27 christo dovecot[216609]: IMAP(frank,127.0.0.1): Fatal: master: service(imap): child 216952 killed with signal 11 (core dumped) Oct 28 11:29:27 christo dovecot[216609]: imap-login: Login: frank, 127.0.0.1, TLS Oct 28 11:29:27 christo dovecot[216609]: IMAP(frank,127.0.0.1): Fatal: master: service(imap): child 216964 killed with signal 11 (core dumped)
For comparison the old version
Oct 28 11:36:58 christo dovecot[279524]: imap-login: Login: frank, 127.0.0.1, TLS Oct 28 11:36:58 christo dovecot[279524]: IMAP(frank,127.0.0.1): ID sent: name=imapsync, version=1.977, os=linux, vendor=Gilles LAMIRAL, support-url=https://imapsync.lamiral.info/, date=23-Dec-2019 20:18:02 +0000, side=host2 Oct 28 11:37:37 christo dovecot[279524]: IMAP(frank,127.0.0.1): Disconnected: Logged out [79451/32883563]
If required here is the configuration which is rather old but worked until 2.3.16

What's going on? Any pointer to solution welcome.
