Nearest I've been to breaking a carbon frame is a gear cable guide popping off (the nice people at Specialized replaced the frame with a later model free of charge). It was 4 years old and had done a lot of hard miles. I currently have 3 carbon frames.
I HAVE broken both steel and alloy frames and not as a result of crashes.....
Most carbon frames seem to be pretty robust, particularly track frames which are comparatively heavy and stiff in order to cope with the added stress of track racing. The only carbon frames I know of with a reputation for breaking are (whisper this) the very light Cervelos.
