ghc: panic! (linkBCO: >= 64k ptrs)
dict is a [String] with around 100,000 entries (around 1.4MB of data), exported from a module Dict. ghci will happily import this module, but any operations on this list (e.g. take 1 dict) fail with a ghc panic. I admit it's perhaps not the best idea to work with a list of this magnitude, but in this case a better error message would be useful.
