Last, on machine B, the time-machine just works.  Maybe it is related to
NVMe and something like [1].

Well, I still do not understand why the time-machine raises an error
when the store have the necessary item.  Any idea?

This looks like something different, but it=E2=80=99s very weird.  The unhe=

It works on all of my machine except my newest one=E2=80=A6

=E2=80=A6and what is different between all my machines and the newest one?

One thing is CPU.  It reminds me the unrelated OpenBLAS failure [1].
Well, the situation is:

* Fail

        i7-10700K  (Comet Lake)

* Build

        i7-6500U   (Skylake)        <-- Ludo ?
        5218       (Cascade Lake)

Bah, I have not idea.  Does it come from

--8<---------------cut here---------------start------------->8---
(define (map/accumulate-builds store proc lst)
  "Apply PROC over each element of LST, accumulating 'build-things' calls a=
nd
coalescing them into a single call."
  (define result
    (map (lambda (obj)
           (with-build-handler build-accumulator
             (proc obj)))
         lst))
[...]
--8<---------------cut here---------------end--------------->8---

where line 1337 is the one with =E2=80=99(map (lambda (obj)=E2=80=99?


Well, it is weird, isn=E2=80=99t?  I am lacking some magical trick to
investigate more.  Any ideas?


Cheers,
simon
