rustdoc ICE: 'no entry found for key' #93476

dhardy · 2022-01-30T11:23:03Z

Running cargo doc --no-deps on nightly causes an ICE.
Judging by my CI runners for PRs this broken between 2 and 4 days ago (26th-28th Jan).

Code

See attached minified project: x.zip. Essentially, this is:

pub extern crate kas_text;

pub mod text {
    pub use kas_text::*;
}

Error output

thread 'rustc' panicked at 'no entry found for key', src/librustdoc/passes/collect_intra_doc_links.rs:929:16

I see the same on docs.rs: https://docs.rs/crate/rp2040-pac/0.3.0/builds/501717

Docs build fine with latest stable (1.58.1), but I get the same error with rustc 1.60.0-nightly (a00e130da 2022-01-29)

Xiretza · 2022-01-30T16:37:57Z

This is probably a duplicate of #93428, right? The fix for that (3903ca1) isn't in yesterday's (2022-01-29) nightly yet, but should be in today's.

dhardy · 2022-01-31T10:39:34Z

I get the same error with rustdoc 1.60.0-nightly (08df8b81d 2022-01-30), which does include 3903ca1.

thejpster · 2022-01-31T14:01:05Z

rustc 1.60.0-nightly (08df8b81d 2022-01-30) works for me on aarch64-apple-darwin, but not on x86_64-unknown-linux-gnu

Nemo157 · 2022-01-31T18:18:06Z

There are definitely three crates still hitting this ICE on docs.rs (at least based on message, and backtrace in 2 cases, but I couldn't reproduce on num-primes when testing locally) in rust-lang/docs.rs#1632.

camelid · 2022-01-31T20:11:43Z

You can use cargo bisect-rustc --regress=ice --start=YYYY-MM-DD --end=YYYY-MM-DD -- doc (https://github.com/rust-lang/cargo-bisect-rustc/) in your code to figure out what change caused this regression.

Nemo157 · 2022-01-31T22:06:51Z

Not so surprisingly bisection reveals #88679 as the cause.

lopopolo · 2022-02-01T02:41:06Z

I'm not sure if this is helpful, but this is the stack I get when attempting to run rustdoc with nightly rustdoc 1.60.0-nightly (6abb6385b 2022-01-26) (which is the most recent nightly available on macOS). I also get the same build failure in CI with rust version 1.60.0-nightly (08df8b81d 2022-01-30).

error: could not document `artichoke-backend`

This error comes from building the docs on artichoke/artichoke@61dc674.

Fixed in #93539.

…pport_rp2040` Building a documentation for `rp2040` currently causes a compiler crash. This is probably related to [rust-lang/rust#93476][1]. thread 'rustc' panicked at 'no entry found for key', src/librustdoc/passes/collect_intra_doc_links.rs:930:16 [1]: rust-lang/rust#93476

Assigning same priority as discussed in the Zulip thread of the Prioritization Working Group.

It seems this issue has regressed recently? Hitting the same ICE on docs.rs.
