I can now replicate these results exactly. I therefore declare this to
be a GHC bug, and will raise the issue on the GHC mailing list. The
assert does indeed stop the bug happening, and I've added a call to
error in Errors.hs if this situation is detected.

Thanks for all your efforts in tracking this down!
