I always get an " Access violation in generated code when reading 0x28900000" error when
executing

> stack haddock haskell-src-exts

since LTS 12.0.

I'm not sure to which project I should submit a bug report.
GHC? Haddock? Or Stack?
And how can I make a smaller case  to reproduce the same error?

I  attached a log when executing with --verbose --cabal-verbose for your info.
