Thanks for the reply, Ben. I guess I'm not 100% sure, as I tried a few variations. Next time I rebuild GHC, I'll take care to record my steps and see what happens. - Conal On Thu, Apr 7, 2016 at 1:52 AM, Ben Gamari wrote:

Luckily, I have a working haddock from 2016-03-07 sources that I copied into my new GHC bin (~/git-repos/ghc-2016-04-05/inplace/bin/) for now.

Hmm, this is quite concerning, especially considering I haven't observed it in my own OS X builds. Are you sure you started from a clean tree (e.g. ran `make distclean`)?

Cheers,
