Hi, I wasn't able to perfectly derive from the log that is linked here if this is the same issue. But it is the same package hitting the same "SigBus due to alignment" issue at a similar time. So I thought dropping a link as FYI might be worth even if eventually they turn out to be different issues.
I've documented for Ubuntu in https://bugs.launchpad.net/debian/+source/netgen/+bug/1919335 And filed the issue upstream at: https://github.com/NGSolve/netgen/issues/89 -- Christian Ehrhardt Staff Engineer, Ubuntu Server Canonical Ltd
