Comment (by CoreyOConnor):

 Reproduced the same crash using a slightly different setup:

 1. uninstalled the haskell platform
 2. removed all haskell software from system
 3. installed ghc using homebrew
 4. re-ran the repro steps I outline above. The same error occurs. I do not
 currently see any difference in the two failures.

 In this case the settings are:

 {{{

 }}}
