 C:\Users\Jonatan\AppData\Local\Programs\stack\x86_64-windows\ghc-8.0.2\lib\process-1.4.3.0\HSprocess-1.4.3.0.o
     The symbol was previously defined in
        C:\sr\snapshots\55a68d16\lib\x86_64-windows-

     This could be caused by:
        * Loading two different object files which export the same symbol
        * Specifying the same object file twice on the GHCi command line
        * An incorrect `package.conf' entry, causing some object to be
          loaded twice.
