GHC 7.4.1 Mac OSX 32 bit gets panic on compilation of Haskell code to C code

[garlicbone]

I run this command: ghc -C s4.hs

And receive the next message

addFlag by -C on the commandline:

Warning: The -fvia-C flag does nothing; it will be removed in a future GHC release

ghc: panic! (the 'impossible' happened)

(GHC version 7.4.1 for i386-apple-darwin):

pipeLoop: at phase As but I wanted to stop at phase HCc

This is the content of s4.hs

import System.Environment -- | 'main' runs the main program main :: IO () main = getArgs >>= print . haqify . head haqify s = "Haq! " ++ s

This has been fixed already:

on the commandline: Warning:
    Compiler not unregisterised, so ignoring -C
