How does confirm that this bug is being hit. `stack haddock
haskell-src-exts` on LTS-12.1 fails with the following cryptic error:

    --  While building custom Setup.hs for package haskell-src-exts-1.20.2

--builddir=.stack-work/dist/x86_64-linux/Cabal- haddock --html
--hoogle --html-location=../$pkg-$version/
    Process exited with code: ExitFailure (-11)
    Logs have been written to:

The log file doesn't contain an error.

How does one upgrade the haddock version and get stack to use it?
