Failed to start mysqld.1

mysqltest failed but provided no output

 - found 'core' (0/0)

Trying 'dbx' to get a backtrace

Trying 'gdb' to get a backtrace from coredump /mnt/buildbot/build/mariadb-10.4.7/mysql-test/var/3/log/binlog_encryption.binlog_incident-mix/mysqld.1/data/core

Core generated by '/mnt/buildbot/build/mariadb-10.4.7/sql/mysqld'

Output from gdb follows. The first stack trace is from the failing thread.

The following stack traces are from all threads (so the failing one is

duplicated).
