Comment (by schyler):

 Solved the problem - for some reason it doesn't flush properly on MinTTY.

 Consider;
 {{{
 -- Small case for #8367

 import Control.Monad
 import System.IO

 main
  = do   -- Print something intelligent
         putStrLn $
              "People assume that time is a strict progression of cause "
           ++ "to effect, but *actually* from a non-linear, non-subjective
 "
           ++ "viewpoint - it's more like a big ball of wibbly wobbly "
           ++ "time-y wimey... stuff."

         -- Uncomment this line to see terminal output
         -- hFlush stdout

         -- Do some pointless logic so the program doesn't terminate and
         -- hence we won't see a buffer flush.
         forever $ return ()
 }}}
 {{{
 #include <stdio.h>

 int main()
 {
         printf("hello");
         //fflush(stdout);
         while (1);
         return 0;
 }
 }}}
 Neither of these work with fflush. Seems to probably be an issue with
 MinTTY/mingw sh, so I'm just going to set to wontfix.

 :(
