I just upgraded to ghc-6.8.3, using a linux binary, and I am having a problem compiling Haddock. Haddock 2.1.0 and Haddock 2.0.0.0 both fail to build under ghc-6.8.3, but they both build successfully with ghc-6.8.2. I don't know if this is a Haddock problem, or a GHC problem, or perhaps something else entirely?

Here is the error I'm getting. It is the same error for either version of Haddock.

[15 of 24] Compiling Haddock.GHC.Typecheck ( src/Haddock/GHC/Typecheck.hs, dist/build/haddock/haddock-tmp/Haddock/GHC/Typecheck.o )

src/Haddock/GHC/Typecheck.hs:82:4: Constructor `HsModule' should have 7 arguments, but has been given 8 In the pattern: HsModule _ _ _ _ _ mbOpts _ _ In a pattern binding: HsModule _ _ _ _ _ mbOpts _ _ = unLoc parsed <snip>

I managed to fix this with a bit of hacking: 1) add "import FastString" to the top of the file 2) remove one of the _'s before mbOpts on that line that gives the error 3) on line 72 of the original file (probably 73 after step 1), insert 'fmap unpackFS' before 'mbOpts'. I now get some sort of System.Process-related link error, though.
