[debian-mysql] Bug#943962: Bug#943962: mariadb-server-10.3: mysqld crashes and hangs, no longer processing requests

[Richard van den Berg]

I had looked at https://wiki.debian.org/HowToGetABacktrace but I might

https://packages.debian.org/search?keywords=mariadb-server-core-10.3
shows mariadb-server-core-10.3-dbgsym to be only available for sid, but
I am on buster.
