I had a running zabbix 4.2 instance for my home network. With opensuse leap 15.2 I installed the provided RPMs for zabbix 5.0(.2). After I fixed the database to use utf8_bin, zabbix did run for a while (a night). After that the server crashed and is now crashing directly after I restart it.

Steps to reproduce:

1. restart zabbix
2. crash ...

Result:
See zabbix log (debug level 5)
See output of objdump

Expected:
running zabbix server

I can (re)start the server if I use an backup of the database (created directly after the new zabbix version was running). However, it also crashes after a certain time.

I would move back to the older release but due to the database conversion / change in the database version this is no longer possible.

Please contact me if any addition information is needed.
