I just reinstalled debian stable 9. A few hours after, I got a crash with the following syslog logs when the crash happen, in /var/log/syslog.
I am indeed using a program called slack for IRC-like chatting. One line mentions slack. So I guess slack triggered an error. The slack version is based on a generic .deb package for all linux distributions from the slack.com website.
The crash totally freezes the computer. There is no way to recover. One cannot open the tti shell using CTRL + ALT + F1. One must reboot using REISUB. This is weird.
The bug also seems related to the nouveau driver...you could violate your innocent, pure system with the filthy nasty proprietary Nvidia driver to see if that stops the crashes.

Is there a way to sandbox that application so that it does not freeze the computer?

The buzzword is "sandbox" lately, I see it everywhere. What does it mean? Is it supposed to keep the sand in the box, or keep the cats out of the sand? I think debian has several ways of containing some difficult programs, but I doubt whether poorly written or incompatible software can be made reliable on stretch without recoding it. Why not use the os it is packaged for?
I searched about the nouveau driver error. People experience different behaviours when changing kernel versions. Besides, nvidia the grapics amnufacturer in my case, has some proprietary firmware that is not part of the nouveau driver.
