What I did:

1. I built Pijul #UMF6N7CZA4CTSPKQ on a FreeBSD laptop.
2. I obtained my dot-emacs repository, which lives at https://nest.pijul.com/jaredj/dot-emacs.
3. I made and pushed three changes. one two three.
4. Back on my Debian machine, with Pijul 1.0.0-beta.4, I pulled the three changes.
5. Pijul crashed on my Debian machine, and I’m going to attach the crash report here.

I don’t see any attach function, so I’m going to paste it.

Try to run pijul-tests on freebsd. Feel free to open new issue if find something wrong. Tests lives here: https://git.envs.net/mpech/pijul-tests

Thanks, will do! In the meantime, I built Pijul #UMF6N7CZA4CTSPKQ on my Linux machine, pulled the same three changes, and it did not crash, but gave this output:

  - Order conflict in "init.el" starting on line 280

I haven’t looked at the conflicts in detail but I’m pretty sure this is exactly what it should have done.

BTW, I have tried ping pong records thru nest between x64 and x86 machines without problems.

Well - I don’t know the exact version I was pulling with, because I don’t see any version tagged 1.0.0-beta.4; but I had used

cargo install pijul --version '1.0.0-beta.4'

to install it. crates.io says that was released on March 1. Anyhow - the point is, I was pulling from nest.pijul.com using an older version than I had pushed from, and once I used the newest version it worked right.

I don’t know what sort of backward or forward compatibility guarantees are supposed to exist at this point in pijul’s life; so there may be no issue remaining here.
