It looks like a simple race condition to me. You are using "waitForProcess pid" to wait for runInteractiveCommand to finish, but you don't seem to have anything that waits for createDefFile to finish.

Whoops, sorry, I didn't read the original post closely enough.

...

main :: IO () main = do (file:_) <- getArgs (_, out, _, pid) <- runInteractiveCommand $ "dumpbin /EXPORTS " ++ file forkIO (createDefFile file out) waitForProcess pid hClose out hFlush stdout
