loadObj: failed
I coded the PrettyStub.hs
file as shown in the Real World Haskell, page 119 and loaded it into ghci. I then proceeded to follow the examples on page 120:
ghci>:load PrettyStub
[2 of 2] Compiling Main ( PrettyStub.hs, interpreted )
Ok, modules loaded: SimpleJSON, Main.
ghci>:show modules
SimpleJSON ( SimpleJSON.hs, SimpleJSON.o )
Main ( PrettyStub.hs, interpreted )
ghci>:type undefined
undefined :: a
ghci>undefined
*** Exception: Prelude.undefined
ghci>double 3.14
ghc: panic! (the 'impossible' happened)
(GHC version 6.10.1 for i386-apple-darwin):
loadObj: failed
Please report this as a GHC bug: http://www.haskell.org/ghc/reportabug
And now I'm here.
