Hi Guix,

For me, emacs-next does not build deterministically. Looking at the
diffoscope output,, it looks like a lot of the difference is timestamps.
However, some, but not all of the .elc files differ, as well as
emacs.pdmp. I believe that emacs.pdmp is created by the new portable
dumper.

I've tried updating to the latest emacs snapshot, 27.0.91, but that still
had the problem. The output from the following is attatched:

$ diffoscope \
/gnu/store/g99agydlksb1xa4zjk4nx3fshpfskq0n-emacs-next-27.0.91-0.c36c5a3-check \
/gnu/store/g99agydlksb1xa4zjk4nx3fshpfskq0n-emacs-next-27.0.91-0.c36c5a3

Best,
Jack

I should add, this is master at commit
26e11cffb983604c813064343e41708b99072e4f

I also just tested emacs 26.3, and that also build non-deterministically.

If this is a known problem, I apologize, but I didn't see it in a search
of the issue tracker. I suppose emacs is a difficult search term.

Best,
Jack
