Thanks for checking. I ran the command again and monitored memfree but it 
was nothing to be worried about.
Here is how I ran the command (note the from-to and where the processing 
was when I captured this status):

username@hostname:~$ sudo weectl database rebuild-daily --from=2021-01-01 
--to=2022-01-01
Using configuration file /etc/weewx/weewx.conf
Daily summaries from 2021-01-01 through 2022-01-01, inclusive, will be 
rebuilt.
Rebuild the daily summaries in the database 'weewx.sdb' (y/n)? y
Rebuilding daily summaries in database 'weewx.sdb' ...
Daily summaries at V2.0. Patching to V4.0
Processed through: 2020-08-28 00:00:00 CEST (1598565600)

It again fails at the same point. I'm sorry to bother you so much with this.
I just tried on a laptop where I run weewx 4.10. The 'wee_database 
--rebuild-daily' fails with same error at same point as on the other two 
systems.
For the record, the RPi is 3B+ running bullseye 32-bit, my desktop is old 
i7-6700 3.4GHz with 8 GB, running Ubuntu 22.04.1. Laptop is i7-7500 2.70 
GHz with 8 GB running Ubuntu 22.04.1.
