This is a real problem for diesel. In cold weather disel gums up, basically turning into wax. You can buy disel fuel winter additive if you have summer disel in the tank when winter comes along. Normally it doesn't happen unless you drive very rarely, though there are reports that some of the VW TDIs get such good mileage that you can run into the problem driving up from, say, Atlanta to Boston on a single tank of gas...
I hadn't heard of it for gasoline though. If Jered's right about it being a different percentage of oxygenate then I would expect the first symptom would be knocking. Most engines have variable timing anyways so that wouldn't really happen, you would just lose a little power and fuel efficiency.
