Comment (by RyanGlScott):

 Actually, I should clarify my previous statement: you will never see an
 `ASSERT` failure on a released version of GHC, since they only appear when
 you build GHC with extra compile-time checks. (I'm guessing you're
 building with the `devel2` build flavour or something similar.) So it's
 not at all surprising that this doesn't fire on 8.6.1.

 Another possibility is that if you built 8.6.1 with `ASSERT`s enabled,
 then you'd also see this failure there. That would be worth a try.
