Alpine 3.20/3.21, x86_64
Description
As of Alpine 3.20 and 3.21, mariadb-backup (installed from Alpine sources) crashes with a segfault. Alpine 3.19 is not affected.
Alpine 3.20 packages MariaDB 10.11.10 while Alpine 3.19 has 10.11.6.
This seems related/identical to MDEV-34388, but affected versions do not match.
I dug a little deeper and compiled MariaDB from source in an Alpine container to check if it could backup it's default databases (see attachments for details).
I found that MariaDB 10.11.9 works fine and 10.11.10 is broken.
I did a bisect on the changes between these versions using the attached files.
It seems that the error was introduced in eca552a1a45959876bd830a45094c03016b33441.

I tested the commit in an Alpine 3.19 container. The result was the same: mariadb-backup crashed with a segfault.
I did not test in glibc-based environments.
Also, I did not test anything but MariaDB 10.11.x.
Attachments:
- lfs64.patch - Required to build MariaDB on Alpine, from the Alpine package source
- Dockerfile - The container image I used to test this
- test.sh - Script to build and test MariaDB inside the container
- bisect.sh - Script to start the container. May be passed to git bisect run.
- mariadb-backup.log - Output of mariadb-backup --backup --target-dir /tmp/backup when it crashes
