This is required as otherwise the game's exception filter will be called after ours. If we didn't handle the exception, the game's implementation, or an exception handler associated to the exception raised by address will take care of it. Unlike the game's implementation, our exception handler does not handle unknown exceptions. We only do the low level stuff reliably.
