Ubuntu 20.04.2 LTS

10.4 is likely affected too

Can you provide more information? Firstly, repeatable test case would be best option. If that is not possible, can you at least provide full error log from both nodes preferable using --wsrep-debug=1. Stack provided does not look correct as there is ::options and then ::on_apply ?

If this is really release build wsrep-lib should have NDEBUG defined and this assertion should not happen.

Description: MariaDB database server binaries

 MariaDB is a fast, stable and true multi-user, multi-threaded SQL database

 server. SQL (Structured Query Language) is the most popular database query

 language in the world. The main goals of MariaDB are speed, robustness and

 ease of use.

 .

 This package includes the server binaries.

Is there any kind of load at all or is this just a upgrade? Do you use rolling-upgrade (i.e. one node in time) or did you just upgrade both nodes?

This is a live cluster with moderate read write split load. This was a rolling-upgrade of one node with no load but the replication. All 4 other nodes (2 of them garbs) are still on 10.4.15. Downgrading the crashing node again to 10.4.15 solves the problem.

Something has gone wrong with build (I assume this is official build) as this assertion should not be there for release builds. Can you do nm /path/to/mariadb/bin/mysqld | grep assert ?

Yes, this is an official build. The mirror used is http://ftp.hosteurope.de/mirror/mariadb.org/repo/10.4/debian

root@srv3 ~ # nm /usr/sbin/mysqld | grep assert

nm: /usr/sbin/mysqld: no symbols

root@srv3 ~ # nm -D /usr/sbin/mysqld | grep assert

00000000015c1192 B debug_assert_on_not_freed_memory

0000000001e5370c B my_assert_on_error

I have seen similar issue in current 10.6 development HEAD, and it has a tentative fix in testing now. However, I thought that the issue should not reproducible in 10.5 and earlier.
@Steve Hunger Do you have log_slave_updates in your configuration? (you should)

Traditional MariaDB Replication isn't used, therfore log_slave_update was off. I enabled it on all nodes and was able to upgrade the same node from 10.4.15 to 10.4.18 without any crash. I will let this node sit around for some time and report back if it's stable now.

Since enabling log_slave_update the node did not crash again because of this issue. There were 2 other crashes, but they are likely related to MDEV-24322 (Failing assertion: UT_LIST_GET_LEN(lock.trx_locks) == 0), so i attached the logs there.
