#901: I/O sequencing problem on OS X/x86

   Component:  Compiler  |      Version:  6.5    
    Severity:  normal    |     Keywords:         
          Os:  MacOS X   |   Difficulty:  Unknown
Architecture:  x86       |  
-------------------------+--------------------------------------------------
The following small program behaves strangely on Mac OS X on x86:

 {{{
 module Main where

 main = do
   putStr "Tell me? "
   response <- getLine
   putStrLn ("You said: " ++ response)

 }}}

 It should print the prompt, wait for input, and then report what it read.
 When compiled to a binary with GHC, however, it first waits for input,
 then prints the prompt and the response together. Strangely, if run inside
 GHCi, it works correctly. It also works correctly under Hugs.
