@virtualritz: Could you post the entire cargo build output, and upload a zip file of your entire target directory somewhere?

[virtualritz]

Could you post the entire cargo build output, [...]

Edited the original. I will update this once target is uploaded. It will take a while. German countryside cro-magnon network infrastructure ...

[virtualritz]

Here you go: https://www.filemail.com/d/lkjfupbexzjtstc

Warning: will expand to >1.5GB.

I also tried a cargo clean & cargo build and a can't reproduced this. Good I took the snapshot.

[apiraino]

Building the code in the repository needs some external dependencies. Perhaps good candidate to try to restrict to a smaller reproducible sample (ideally, independent) - is it possible @virtualritz to try isolating the code causing the panic?

@rustbot ping icebreakers-cleanup-crew

Please let @rust-lang/release know if you're having trouble with this bot.

Hey Cleanup Crew ICE-breakers! This bug has been identified as a good
"Cleanup ICE-breaking candidate". In case it's useful, here are some
instructions for tackling these sorts of bugs. Maybe take a look?
Thanks! <3

The problem is, this is an incr compiling error. @virtualritz do you know what you have done before you did cargo build, e.g. renaming a struct, adding a type to a trait, ...?
This kind of errors do occur if you have state A, change something and build state B without doing cargo clean in the meantime.
They are somewhat hard to figure out. I'm downloading your target folder to see, what I can do, but I don't have high hopes here if you can't provide additional information :/

edit: no luck with the downloaded zip file :( let's see what we can do here

[virtualritz]

As I said, I can't reproduce this. After a cargo clean cargo build just works.

I ran into it when I noticed I broke some example. So I went back to the first commit I made after forking the repo. When I did a cargo build after the git checkout I ran into this issue.

I.e. no code was changed by me. Git changed the code from the commit I was on back to the commit in question.

And no, as I have zero idea where this came from I can't make a minimal repro case.

[Aaron1011]

This should be fixed by #83901, but I haven't been able to create a minimal reproducer.

[camelid]

Should that PR be marked as fixing this issue so we don't forget to close this issue?

[apiraino]

Removing I-prioritize and adding a label to explicit we are waiting for a feedback (if possible) from issue reporter. Else we might want to consider this as closed (and reopen if it's not the case).

@rustbot label -I-prioritize +S-waiting-on-author

[virtualritz]

I have not ever seen this again with newer nightly versions.
