Using hdevtools caused "Evaluated the place holder for a PostTcKind"
I was tying to get hdevtools to work, and cloned it and pulled in a bunch of the open pull requests. You can see the state it's in at github.com/tbelaire/hdevtools.
git clone git@github.com:tbelaire/hdevtools
cd hdevtools
cabal sandbox init
cabal install
cd ..
I could not reproduce the problem on a small test file, so I'm afraid I'll have to demonstrate it on my vinyl-json package.
git clone git@github.com:tbelaire/vinyl-json
cd vinyl-json/
cabal sandbox init
cabal install
hdevtools type src/Data/Vinyl/JSON.hs 42 15
panic! (the 'impossible' happened)
(GHC version 7.8.20140130 for x86_64-apple-darwin):
Evaluated the place holder for a PostTcKind
Please report this as a GHC bug: http://www.haskell.org/ghc/reportabug
I also get hpc has closed due to a problem a lot when compiling things, but I think that's unrelated. The dynamic lib seems to be gone.
