UndecidableInstances a.k.a. YouDecidableInstances.
While I was writing the Prelude, I messed up one of the definitions and ghc kept blowing the context stack limit. So I tried it with -fcontext-stack=5000, figuring it wasn't my bug but just a consequence of the inefficient encoding I was using. The type system ended up allocating upwards of 4 gigs before I killed it.
