Subject: Julia packages are not reproducible

Currently Julia packages, as built with Julia 1.8.3, are not
reproducible.  Here’s a small sample:

For what it's worth I had been running into reproducibility issues with a couple of Julia packages I was working on as well, one example being https://issues.guix.gnu.org/72896. I assume the cause is the same as what you're seeing here.

Best,
Spencer

Well, IIRC, upstream was not receptive about tackling that problem, see
upstream issue#34753.

    https://github.com/JuliaLang/julia/issues/34753

Somehow, it’s seem the same kind of situation as Guile and
non-reproducible .go. ;-) Tackling the problem implies a deep-dive into
the compiler’s internals that requires a lot of efforts without the help
of core upstream.

Please note that Julia had been removed from Debian on 2022 [1], thus it
does not seem under the radar of ReproducibleBuilds.

Cheers,
simon
