*You don't even know what you mean by this*
What I mean is the execution trace that is derived
within the semantics of the C programming language.

HHH1 simulates DDD that calls HHH(DDD) that
simulates DDD and then simulates itself simulating DDD.
Then HHH(DDD) aborts its simulation and returns to the
DDD simulated by HHH1. Then this DDD returns to HHH1.
