A handful of new failures appeared in the nightly build recently, perhaps as a result of the changes to unboxed tuple handling. The failures are all with GHCi.

I think I fixed this with my commit ad6af5fc6db334a373ef3b7cca72143a8bf6b459

I'm still getting some validate failures (see below) but I can reproduce them with the commit directly before my unboxed-tuple branch was merged in, so I think they are unrelated to my changes:
