Segmentation fault during init

Hi,

I’m trying to upgrade our rather old 3.8.8 installation to newer version, so I thought I would start again with a clean VM (debian buster 10 + mariadb + nginx + rt4-fcgi) and managed to install it okay, however, when trying to initialise the database, I get a segmentation fault.

If anyone can help shed any light on it, would be appreciated. I notice similar errors have been reported in the past, but none of these seem to quite apply in my case.

I can get the web interface to appear, but it errors out and doesn’t seem to have set up a root user/password in the database.

The upgrade process also seems to have issues: (which is why I started with a fresh database.)
