I just had the same thing occur. I hunted down the cause to one file that caused the error even when empty. Examining the file, I discovered it had the wrong character set. When I set it to UTF-8, the error vanished. I think that it was decoding it with the wrong character set.

From this I surmise that the error simply indicates that something has happened that the compiler was unprepared for. Sorry that isn't very helpful to most people, but it may help to check your characters sets.
