Dear Maintainer,
lshw crashes with SEGV in privileged containers in Ubuntu, unless you
disable the 'usb' test as follow :
$ lshw -disable usb
Note that the problem isn't reproducible in Debian because the container
image doesn't contains the 2 files from where lshw try to get
informations :
/proc/bus/usb/devices
/sys/kernel/debug/usb/devices
thus stop at the following lshw verification :
if (!exists(SYSKERNELDEBUGUSBDEVICES) && !exists(PROCBUSUSBDEVICES))
return false
but in Ubuntu, lshw segfault in a privileged container because the
actual lshw code only look if both doesn't exist or one of them is
inaccessible (EACCESS).. then lshw segfault.
For more informations about the Ubuntu bug :

Despite the fact that debian doesn't exhibit the situation, I think it
would be great to consider this lshw PR since Ubuntu or other
distributions relies on Debian for packages (merge, sync, ...) :
https://ezix.org/src/pkg/lshw/pulls/9
The change is trivial, and only introduce a better mechanism to validate
possible scenarios :
if both files doesn't exist
if 1/2 file exists
if files can't be opene (EACCESS)
....
