Chapter 28 in Beautiful Code (http://www.amazon.com/Beautiful-Code-Leading-Programmers-Pra...) talks about delta debugging, how it was invented and developed. its really a great chapter in a great book. i can't recommend it enough.



This chapter actually has a much cooler implementation of delta debugging that what has been discussed here. We're generally thinking of delta debugging in which we take the changes to the source as the search space and use some form of binary search to find the offending change (for which git bisect is great). The chapter in beautiful code begins with this but then moves on to runtime delta debugging in which the techniques are used to compare the memory in use by two instances of the program (one buggy and one not) until a specific piece of the programs state can be isolated as the cause.
