Binary.get(TyClDecl): ForeignType

    ghc: panic! (the 'impossible' happened)
      (GHC version 8.0.2 for x86_64-unknown-linux):
        Binary.get(TyClDecl): ForeignType
    CallStack (from HasCallStack):
      error, called at compiler/iface/IfaceSyn.hs:1530:18 in ghc:IfaceSyn

Steps to reproduce:

Download a 640 Mb zip archive from https://drive.google.com/file/d/0B0Jnpz9ldbuHZHI4NFB3XzBucVU/view?usp=sharing. Unpack it. Inside are two directories:

home_stack (du -s reports size 2691340 Kb)
cardano-sl (du -s reports size 639820 Kb)

Move home_stack to ~/.stack, deleting the original directory if it exists.
Move cardano-sl to ~/repos/cardano-sl.
cd to ~/repos/cardano-sl.
Issue stack build --flag cardano-sl:with-explorer --ghc-options -fprint-potential-instances. (Should also reproduce with stack build alone, but the following output is from the longer command.)
