A method for debugging a program includes executing, by a computing platform, a given program with a plurality of loops. Each of the plurality of loops includes multiple candidate iterations, and each loop in the given program includes a set of executable statements. A particular loop of the plurality of loops can include at least a particular iteration and one or more other iterations. The method can also include executing at least the particular iteration and the one or more other iterations for the particular loop. During execution of at least the particular iteration and the one or more other iterations for the particular loop, information that indicates which iteration of the particular loop is being executed is stored. Further, the method includes discarding temporarily stored information about the one or more other iterations without storing the information in the log.
