error: could not compile `dleq`
warning: build failed, waiting for other jobs to finish...
error: build failed
user@computer:~/dleq-rs$

Encountered while working on a project of mine. I copied the directory to another location to back it up, and went there to confirm the same command exhibited the same behavior. The changed path triggered a rebuild and this caused rustc to work without issue, leading me to believe there's a malformed cache. I have been updating my Cargo.toml, from additions to removals to even a version upgrade. That said, my only change before my last successful compile and this one was introducing a few errors while I expanded functionality. I was hoping my malformed code would offer a MRE, yet unfortunately (or fortunately) Rust can handle it.

I am on nightly and went to the latest nightly to check this was still an issue. Doing so rebuilt my cache yet again, hence why my version info is what it is (it's rustup's logs on what it upgraded from). I do have a copy of the cache directory, as it caused errors, I'd be willing to send privately if it'd be beneficial. I never directly edited it. As for the code edits, those would be harder to track down due to the fact I'm in the middle of a commit, and can't confirm what my code was on the last successful compile in order to provide such a diff.

[kayabaNerve]

I just realized this asked for RUST_BACKTRACE=full and I provided RUST_BACKTRACE=1 (as I was already using that on my tests), sorry. If there's a command I can use to revert my Rust install in a way that won't trigger a rebuild when I try it against my preserved faulty cache (which I'd have to move back to its original position, of course), I'm more than willing to run it and provide the proper backtrace.

[pr2502]

The top of the stack trace seems identical to #89260

[teor2345]

I'm still seeing an ICE with a very similar backtrace.
It's also similar to #89260.

It happens when building https://github.com/ZcashFoundation/zebra , but only when the on-disk cache is in a particular state. (Approximately every ~100 builds.)

So I can't provide an easy reproduction.

I'm using:

error: internal compiler error: unexpected panic

note: the compiler unexpectedly panicked. this is a bug.

note: we would appreciate a bug report: https://github.com/rust-lang/rust/issues/new?labels=C-bug%2C+I-ICE%2C+T-compiler&template=ice.md

note: rustc 1.57.0-nightly (25ec82738 2021-10-05) running on x86_64-unknown-linux-gnu

note: compiler flags: -Z share-generics=y -C embed-bitcode=no -C debuginfo=2 -C linker=clang -C incremental -C link-arg=-fuse-ld=lld

note: some of the compiler flags provided by cargo are hidden

Possible dupe of #91696. Hopefully fixed by #91919.

@rustbot label +A-incr-comp

[workingjubilee]

Closing assuming the previous "it's a duplicate" is correct, because it seems so to my eyes. Should be fixed by either that or #93064
