My read of the postinst is that it correctly chmod's /var/crash
regardless of whether it did the creating:

                mkdir -p -m 3777 /var/crash
                chmod g+s /var/crash
                chgrp whoopsie /var/crash


I've confirmed that 'mkdir -p -m' doesn't change the mode of an existing 
directory.  And /var/crash has been on my system since 2019 when this system 
was installed, so it's not new here?

Running `dpkg-reconfigure whoopsie` (i.e., triggering a rerun of the
postinst) is sufficient to fix the directory permissions.

But it must have been something else besides the apport postinst that
dropped the g+s bit.
