While developing Yesod project on GHC 7.8.3, `cabal install --force- reinstalls` failed with the following error:

{{{ [9 of 9] Compiling Application ( Application.hs, dist/dist-sandbox- e4ea4713/build/Application.o ) ghc: panic!

Please report this as a GHC bug: http://www.haskell.org/ghc/reportabug

(Full output at https://gist.github.com/MaxGabriel/847561107e4ee2e869f1. Verbose output at https://gist.github.com/MaxGabriel/10c2c3c253815b3f392a)

Following compilation, both aeson-0.8.0.1 and aeson-0.8.0.2 are present in the sandbox. Running `cabal install` again yields the same error (full output at https://gist.github.com/MaxGabriel/9aa530105d68a613de11).

The code for the project as it was when the panic happened is available here: https://github.com/MaxGabriel/MyBlog-GHC-Panic

Is there more information I could provide to diagnose the bug?

I'll probably wipe the sandbox and try recompiling in a bit.

The reinstall that triggered the panic was under Yosemite. -- -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9704#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
