Comment (by bgamari):

 I would say that this really isn't a GHC so much as it is a `pureMD5`
 issue. While it's pretty reasonable to request that GHC inline the
 `unsafeUseAsCString` form of `getNthWord`, the `cereal` version produces
 far too much code to be worth inlining. Despite this, the library forces
 GHC to inline in both cases, hence the explosion during simplification. I
 have opened a [[https://github.com/TomMD/pureMD5/pull/3|pull request]]
 fixing this upstream.

 I haven't yet looked at the `chatter` issue.
