Relative Debugging requires users to identify the corresponding data structures within the two programs, and the locations at which the comparisons should be performed. To quickly and effectively identify useful data structures and comparison points requires that users have a detailed knowledge of the two programs under consideration. Without a detailed knowledge of the two programs, t...
