ICE: Found unstable fingerprints for mir_built #107665

Code

A little backstory: this issue ended up fixing itself while I was attempting minimization, so I'm not sure if this bug report is still useful, as I don't know how to replicate the error anymore. I saved a commit when I found the error, but even reverting to it doesn't cause this bug to pop up again. The command used to test was either cargo test or cargo test --bin server my_fn.

At the same time, this was an ICE, so I believe it may still be worth reporting.

What ended up fixing things was turning use super::* to use super::{only_the_imports_I_need} so I believe there was something that super::* was bringing in that was breaking things. Hereafter, when I say "accidentally fixed the issue" I'm referring to this fixing of imports.

In practice, this is what I was testing (with identifiying information obfuscated):

#[tokio::test]
async fn my_fn() {
    let uid = PERSON_UID;
    let org_id = OID(5555555);
    let result = org::my_fn(uid, org_id).await;
    assert!(result.is_ok());
}

Where org was a module in my project. While minimizing, I brought all the non-external code into that one function my_fn, and still received the error. I'm not including it all since I also found that only this test also caused the error:

fn it_works() {
    assert_eq!(2 + 2, 4);
}

I'm including the former still it gives some context but because I believe this was caused by something in super::* I would ideally submit literally the entire program ---- but since "literally the entire program" is no longer causing the bug to happen for me, I'm not sure what to do. (Literally the entire program in the sense that if I run cargo test now, with the git-reverted version of my program, I don't get the same error again.)

I was still able to test the three main channels before accidentally fixing this though:

Meta

rustc --version --verbose:

rustc 1.66.1 (90743e729 2023-01-10)
binary: rustc
commit-hash: 90743e7298aca107ddaa0c202a4d3604e29bfeb6
commit-date: 2023-01-10
host: x86_64-pc-windows-msvc
release: 1.66.1
LLVM version: 15.0.2

Since this section also asked about the nightly and beta versions, I found the following behavior for both of them: cargo test passes both tests I have, but cargo test -- --my_fn returns:

error: Unrecognized option: 'my_fn'
error: test failed, to rerun pass `--bin server`

So when I then use cargo test --bin server --my_fn the test passes fine.

Nightly version:

rustc --version --verbose
rustc 1.68.0-nightly (3020239de 2023-01-09)
binary: rustc
commit-hash: 3020239de947ec52677e9b4e853a6a9fc073d1f9
commit-date: 2023-01-09
host: x86_64-pc-windows-msvc
release: 1.68.0-nightly
LLVM version: 15.0.6

Beta version:

rustc --version --verbose
rustc 1.68.0-beta.2 (10b73bf73 2023-02-01)
binary: rustc
commit-hash: 10b73bf73a6b770cd92ad8ff538173bc3298411c
commit-date: 2023-02-01
host: x86_64-pc-windows-msvc
release: 1.68.0-beta.2
LLVM version: 15.0.6

For the record, cargo test --bin server my_fn gives what looks like the same error (as cargo test) on stable. After I accidentally fixed the issue, all three versions are not showing the error. (This was before I accidentally fixed the error)

This was the first time I'm submitting a bug report for anything, so any feedback is appreciated. Thank you! And I apologize once more that I'm unable to find a code snippet which replicates the error. Unreplicable errors are the worst.

jhwgh1968 commented 1 year ago

I, too, have hit this bug with a similar import error, code change, recompile cycle.

Good news: by coincidence, I made a ZFS snapshot of the filesystem minutes after it happened. I can restore that and repro at will.

Bad news: it seems like if I change anything it invalidates the cache, recompiles properly, and goes away.

I was planning to trim files in target/ until it was a managable size and then privately offer a tarball to a rust dev who would look at it. But now I'm not sure I can actually ship my reproducer directory properly.

Any tips for making this into a docker container? What environment does it check?

EDIT: I'm on stable, 1.66.1

jhwgh1968 commented 1 year ago

I have figured out how to make a docker container which reproduces the problem. I did it by nailing down a couple env vars, and copying way too much of my home dir into it.

I will prune it down procedurally to something much smaller. Hopefully I'll have a perfect reproduction within the next week or two that is not immensely bloated.

jhwgh1968 commented 1 year ago

I have successfully created a Docker container which reproduces the problem, based on some code of mine that is not ready for the public. But I'd be willing to send it to a compiler dev for examination.

After significant pruning, the container is ~0.5GB compressed (~1.6 GB uncompressed). But keep in mind it is completely self-contained, so that includes the entire toolchain which reproduces the problem (the then-newest stable).

I'll offer a file sharking link privately via e-mail to any rust dev who would take this issue up.

Pinging as first ideas:
