Comment (by hvr):

 btw, note that `(^)` for `Integer` is implemented via square-and-multiply,
 c.f. [http://hackage.haskell.org/package/base-4.6.0.1/docs/src/GHC-
 Real.html#%5E implementation in base].
 So it might be interesting if one could find out which one of the several
 `Integer`-primop calls involved causes the actual fault.
