When we stipulate that the only measure of a correct emulation is the semantics of the x86 programming language then we see that when DDD is correctly emulated by H0 that its call to H0(DDD) cannot possibly return.

When we define H1 as identical to H0 except that DDD does not call H1 then we see that when DDD is correctly emulated by H1 that its call to H0(DDD) does return. This is the same behavior as the directly executed DDD().

 Right, so what does a call to a location of memory that doesn't exist do?

Liar
When we stipulate that the only measure of a correct emulation
is the semantics of the x86 programming language then we see
that when DDD is correctly emulated by H0 that its call to
H0(DDD) cannot possibly return.
