When we hypothesize that the code at machine address 0000213c is
an x86 emulator then we know that DD remains stuck in recursive
emulation and cannot possibly reach its own "ret" instruction and
terminate normally.
When we add the additional complexity that HHH also aborts this
sequence at some point then every level of recursive emulation
immediately stops. This does not enable any DD to ever reach its
"ret" instruction.

all besides DD EMULATED BY HHH

HHH emulating DD fails to reach the 'ret' instruction.

 
Because DD calls HHH(DD) in recursive emulation thus non-termination is
entirely the fault of DD.
