What an excellent idea! I think the right approach here is to build on the stepper’s model; it should already include all of the information that you need to build this trace (well, almost… there may be heap identity issues). Indeed, I had an undergraduate who worked on this a few years back. He didn’t get very far, I’m sorry to say. Would you like me to send you his code? I’ll have to check with him first.
