[jieyouxu]

Does it still ICE if you clean the build cache and try again? Might be an incr-comp bug.

[Buckram123]

Does it still ICE if you clean the build cache and try again? Might be an incr-comp bug.

Just got similar error with fresh build, noticed this issue is fresh, so maybe it is related. Will post my error and backtrace as well

Just got similar error with fresh build, noticed this issue is fresh, so maybe it is related. Will post my error and backtrace as well

Yeah, unfortunately if it's an incr-comp bug, sometimes yeeting the build cache will make it magically go away and then we can't reproduce it. Does your build still ICE if you yeet the build cache and try building again?

Yeah rm -rf ~/.cargo/registry/src/ helped with this, thanks! Would be useful to have it in the error itself, if possible

[jieyouxu]

The idea is that we don't have this in the error itself, because we want people to report incr-comp bugs. Sometimes a bug can also seem like incr-comp bugs but are in other areas, it's hard to tell without having a repro + backtrace.

[saethlin]

This is not an incremental compilation bug. I know that in this case because at the bottom of an ICE we print the compiler flags and there's no -C incremental=[REDACTED].

But more broadly, please read the Zulip topic I started here: https://rust-lang.zulipchat.com/#narrow/stream/122651-general/topic/Out-of-disk.20issues.20are.20easy.20to.20confuse.20with.20incr.20comp

[vatsa287]

@saethlin @jieyouxu Thanks for quick updates.

This issue was solved with cargo clean.

What bugged me was that this was on a fresh build, with no pre-existing binaries.

Hm, it broke again and removing rm -rf ~/.cargo/registry/src/ doesn't fix it

[jieyouxu]

As saethlin mentioned above, are you sure you're not running out of disk space?

[Buckram123]

Hm, it broke again and removing rm -rf ~/.cargo/registry/src/ doesn't fix it

As saethlin mentioned above, are you sure you're not running out of disk space?

Yes, I'm pretty sure. I have ~90 more GiB
Also at the bottom of error I have compiler flags included as well, and some other information

note: compiler flags: -C embed-bitcode=no -C debuginfo=2 -C incremental=[REDACTED]

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

query stack during panic:
#0 [resolver_for_lowering] getting the resolver for lowering
end of query stack

[jieyouxu]

Wait, I didn't pick up that you're doing rm -rf ~/.cargo/registry/src/ initially. Doesn't that just remove the cargo registry sources for your dependencies? By clearing the build cache I meant cargo clean on your project. If you can still produce an ICE after that, then please kindly report that in another issue, as your issue might seem similar to vatsa287's issue, but they don't necessarily have the same root cause.

Yesterday decided to try clearing registry sources, before cargo clean, because cargo clean was not enough. And today, just managed to fix it by clearing cache of sccache as well. Thanks for quick and helpful responses! Will create new issue if I get this error again

[saethlin]

The root problem here is that you have/had a truncated rmeta file. In general I think that's most commonly caused by running out of disk, but the output system in rustc (is supposed to) stop trying to write if in I/O error is encountered, but continue compilation as if nothing is wrong until we would finalize the output file, and then only then report an error.

One of the problems I've merged fixes for was that the compiler would report success when actually it encountered an I/O error and stopped output. I'd expect that under such circumstances, a caching system like sccache would then cache a broken build artifact. That problem exists in 1.75, the version you are using.

This whole system around I/O errors was quite broken for many releases, but in 1.77 (will be stable in 16 days) it finally passes a basic simulation of a spuriously-failing disk.

[saethlin]

I think the root cause of this issue was rustc incorrectly handling/reporting I/O errors. I've landed a number of PRs to address the problem; the most recent of those is #119510 which is now part of the latest stable toolchain, 1.77. Therefore, even though I have not reproduced exactly what you've reported here, I'm going to close this because I am reasonably confident that this bug is now fixed on stable.

Of course it is possible that I am wrong and the bug you've reported here is not fixed. If you happen to run into problems like this in 1.77 or later please do not hesitate to open a new issue.
