Every GHC-compiled program seg-fault (HEAD)

Travis can't build on Windows, I'm afraid.

I'm sort of mitigating another crisis right now, but here's a shot in
the dark - based on my Very Amazing Deductive Skills[1], completed in
mere seconds, I'm guessing that perhaps
e68195a96529cf1cc2d9cc6a9bc05183fce5ecea is relevant, one of Simon's
latest commits? e.g., just try, as a shot in the dark

$ git revert e68195a96529cf1cc2d9cc6a9bc05183fce5ecea

And build again.

[1] Note: my Very Amazing Deductive Skills in this case, are as
follows. Look at git log for the last few days. See that some C code
was changed. Immediately become suspicious that is the culprit,
because it's C code. So, yes, a complete shot in the dark, but it's
one that's served me well, too. :)
