The bug is not reproducible, so it is likely a hardware or OS problem.

Still nothing in /var/crash to report :-/
Why is that - I have apport/whoopsie installed, the kernel is set up
$ sysctl -a | grep core_patt
kernel.core_pattern = |/usr/share/apport/apport %p %s %c %d %P %E
Also I have set
$ cat ~/.config/apport/settings
[main]
unpackaged=true
This is armhf lxd on arm64 host - maybe apport has a guest/host problem
here?
@Doko - do you happen to know if there are any extra whoops to jump
through to get a crash report from gcc when it crashes in debuild?
