bug#55639: time-machine back in 2020: weird error

[zimoun <zimon.toutoune@gmail.com>]

Re,

Maybe the issue is coming from the old Guile 3.0.2 of 2020 not
supporting some recent CPU…  Well, I do not know.

Any idea for debugging?  I already have tried to remove the potential
bugs between the chair and the keyboard. :-)
