Steps to reproduce:

Unfortunately I don't have a way to demonstrate it all the time like a step-for-step plan.

But one of my latest crashes was while listen to this video:

Bug 1336229 does not fix this bug in 2017-02-06 build. You need to have the experimental YouTube material design UI to reproduce the crash.

Copying from my another comment in bug 1315232 comment 12:
(For the MD UI) There is an exit icon on the bottom right corner for quitting the MD UI. The left sidebar is hidden by default. It dims the main content when I open the sidebar.

I do not know how to enable MD UI. It was enabled some time ago and I just never quit that (in Firefox; I quit in Chrome and cannot get it back).
I think the UI choice is now tied to my Google account instead of a cookie value. I open YouTube in a new profile and get the standard UI. Once I log in with my Google account, I get the MD UI (and it crahses...) despite having a different value for the cookie VISITOR_INFO1_LIVE from the one in my main profile and an old tutorial [1] I find on the web.

Maybe you can ask Google to enable MD UI for a Google account for testing purpose?

I'm using a x86_64 platform so I'm not sure if this issue is really _86 specific.
