mysqld got exception 0xc0000005 in mark_select_range_as_dependent()

11.4.10-MariaDB installed over 11.4.2-MariaDB home and service is crashing since right after startup. Installation went smoothly without any error.
I started to investigate. ERR log was non-informative. I commented several my.ini lines, so finally I got service started. Then I found that it deals with events, because with

event_scheduler=1

commented it starts the service OK.
I have a number of events from previous (11.4.2) development.
So I altered all events to disable and uncommented event_scheduler switch. And then the service started OK. If I reenable events, it falls again. Then I started to enable events one by one. Then I found the one that crashes the service. It calls my procedure. I executed the procedure call manually and the service crashed. The procedure and event were working fine in 11.4.2. Then with events disabled I recreated the procedure using Heidisql. It was recreated fine without any error. Then I called the procedure again and the service crashed again immediate.
I'll attach dumps, err log quotes and procedure source.
