 *It is a basic fact that DDD emulated by HHH according to*
*the semantics of the x86 language cannot possibly stop*
*running unless aborted* (out of memory error excluded)

 It is obfious from both the C code and disassembly listing
that DDD cannot return if HHH doesn't (but can and does
otherwise). Whether HHH returns is not obvious as the details
of HHH is not shown and most of its behaviour is unspecified.
 

 That HHH <is> and x86 emulator <is> sufficient to
determine exactly what the behavior of DDD emulated by HHH
according to the semantics of the x86 language would be.

If HHH is merely an x86 emulator then obviously HHH(DDD) does not
return (instead it crashes for trying to use too much memory) and
therefore DDD does not return, either.
