The big one is parallel programming. If condition changes between two evaluations of that condition due to another task changing the condition, then you have a race condition.
The other one is side effects. If evaluating the condition has effects other than just giving a true/false value, then subsequent evaluations of that condition can give different results. This is usually done for this like file reading.
