Local Halt Decider: Infinite Recursion Detected Simulation Stopped
The trace does not show that HHH returns so there is no basis to
think that HHH is a decider.
The trace shows the data of the executed program of HHH that
does halt.
It shows some of the data, not all, and in particular, not the halting.

DDD emulated by HHH according to the semantic meaning of
its x86 instructions never stop running unless aborted.
The abortion is shown but not any reason to abort.
