mysqldump --all-databases causes segmentation fault

    Details

      Description

      I am running a mysql 8.0.15 docker container. I have a separate container running Alpine Linux 3.9, in which I install both mariadb-client and mariadb-connector-c.

      In the server I set up an empty databases `tester`. I then run:

      • `mysqldump -h mysql -uuser -pabcdefg --databases tester` - this works
      • `mysqldump -h mysql -uuser -pabcdefg --all-databases` - this crashes with a segmentation fault

      / # mysqldump -h mysql -uuser -pabcdefg --verbose --all-databases
      -- Connecting to mysql...

      Segmentation fault
      

      Unsure if the `mariadb-connector-c` install is affecting it somehow (although I need it for the caching_sha2_password plugin); it is an issue with the Alpine package, or something else.

      FYI, the Alpine package source is here https://git.alpinelinux.org/aports/tree/main/mariadb?h=master
