dovecot - Oct 2020 - Testing with imaptest to non existing folder makes imap service crash

FWIIW I had this message still in drafts

/usr/bin/imaptest - append=100,0 logout=0 host=xxx port=143 user=xxx 
pass=xxx  seed=100 secs=1 clients=1 mbox=64kb.mbox box=inbox/test 
msgs=100000

And inbox/test does not exist, results in:

 Fatal: master: service(imap): child 20282 killed with signal 11 (core 
dumped)

Can you provide the core file using dovecot-sysreport tool?

https://raw.githubusercontent.com/dovecot/core/master/src/util/dovecot-sysreport

dovecot-sysreport --core /path/to/imap /path/to/core 

Make sure you have gdb and dovecot-dbg installed for best results.
