[Haskell] strange ghc behaviour?

Thanks for the information. I have ran the apple hardware test and it  
reported that there were no errors with the RAM (although I'm not  
convinced there is nothing wrong with the RAM). Perhaps it could have  
been a problem with the ghc installation (i.e. a bit got flipped in  
the executable during build).

Is it possible to uninstall ghc?
