Sure it can. I have shown an H0 that does so.

Nope, since you didn't put in the rule, and if you had it would have shown that you lied, as if H0 is a pure function then the call to H0 emulated by H0 needs to have the same behaivor as the direct call to H0 by main.

Incidentally, the nonconformance you're referring to is shown explicitly in the "195 page trace" that PO linked to. [I.e. the simulated H does not correctly track the code path of the outer H.]

I suppose I should have made clear, that's not simply due to the simulated H being aborted. There is an instruction in H: [actually, in Init_Halts_HH()]

Would need to look closer at the code, but I bet that the simulated machine is looking into the trace buffer to see if it is simulated or not.
Has PO published the C code for the trace? Anyhow, given that its in Init_Halts_HH(), I expect its a global area being initialised - probably the global trace table.
In effect, it is misusing static memory just like he says isn't allowed.
Right.
Mike.
