Using stackage's lts-12.4, which includes version 1.20.3.
Building Haddock documentation locally with stack, I get this:

stack haddock --open haskell-src-exts

It looks like the problem is in different settings in Stack - it hyperlinks sources by default, I get the same result with new cabal commands using the latest at this moment comit e0f2aa8 -

mpickering commented

Seems like a bug in haddock to me?

qrilka commented

Looks like it was resolved in GHC 8.6.1

qrilka commented

stack haddock fine for me with lts-13.0

damiencourousse commented

yes, it's also fine for me with lts-13.0
thanks!
