While the pass is not part of the default pipeline, some people use it (and apparently breaks).
That said, on a second thought, I decide to withdraw my request to backport this as it doesn't seem there's a reason strong enough to do that.
Also, the crash has been there since forever as far as I can tell, in fact I can reproduce it pre 3.9.
