 Windows shows a window that says "GHC has stopped working" when compiling
 a simple hello world.

 Steps to reproduce
 1) Download GHC 7.8 RC2
 (http://www.haskell.org/ghc/dist/7.8.1-rc2/ghc-7.8.0.20140228-i386
 -unknown-mingw32.tar.bz2)
 2) Extract the contents of the tar to folder $GHC$
 3) Add $GHC$\bin and $GHC$\mingw\bin folder to the PATH, add env var
 "LANG=C".
 4) Create file test.hs with contents:

 main = putStrLn "Hello, World!"

 5) run "ghc test.hs".

 Interestingly, the error is not deterministic, ie, after running the
 command several times the program gets compiled. When that happens, and ff
 the file test.o is not deleted, further attempts to compile run
 succesfully.

 GHCi appears to work normally (when doing simple tests).
