[Haskell-cafe] Access violation when stack haddock haskell-src-exts since LTS 12.0

[Shao Cheng]

Hi Yamamoto-san,

I've encountered the same problem before, and there's a haddock issue
tracking this problem: https://github.com/haskell/haddock/issues/837. A
simple fix is building latest version of haddock and replacing the haddock
binary for ghc-8.4.3.
