Comment (by RyanGlScott):
Here's a much more minimal example:
{{{#!hs
{-# LANGUAGE TemplateHaskell #-}
module Bug where
import GHC.StaticPtr
import Language.Haskell.TH
main :: IO ()
main = putStrLn (deRefStaticPtr $(pure (StaticE (LitE (StringL "wat")))))
}}}
I don't know too much about the subtleties of static pointers, but perhaps
the simplest fix would be to add an extra check to see if
`-XStaticPointers` is enabled before using them in Template Haskell?
