Output filename collisions and ICE with 'cargo doc' on 1.38.0 #65367

ebkalderon · 2019-10-13T10:27:55Z

Summary

I was attempting to run cargo doc --open at the top level of a Cargo workspace, which resulted in several warnings regarding output filename collisions for lexical-core, proc_macro2, quote, syn, and unicode-xid (rust-lang/cargo#6313).

Later on, there is an internal compiler error caused by lexical-core 0.4.6:

error: internal compiler error: src/librustc/hir/def.rs:339: attempted .def_id() on invalid res: Err

thread 'rustc' panicked at 'Box<Any>', src/librustc_errors/lib.rs:644:9
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace.

This issue only occurs in cargo doc, as far as I can tell. Running cargo build, cargo run, and cargo bench all behave as expected.

Toolchain information

After further investigation, it seems unlikely that this ICE has anything to do with Cargo workspaces. This bug appears to be isolated to the nix-parser crate.

Removing the nix-parser crate from the workspace members, entering the nix-parser subdirectory, and running cargo doc --open still results in the same ICE:

error: aborting due to previous error

One thing to note here is that nix-parser depends directly on lexical-core 0.6.2 and nom 5.0.1, which transitively depends on lexical-core 0.4.6. I wonder if the output filename collision occurring in lexical-core is causing the problem here?

ebkalderon · 2019-10-13T10:50:25Z

Also, I should mention that running cargo build, cargo run, or cargo bench at either the repo root or in the nix-parser subdirectory do not result in "output filename collision" warnings. The bug causing this ICE appears to be localized to rustdoc and/or cargo doc.

jonas-schievink · 2019-10-13T11:09:18Z

Does it also happen on nightly? Is there an older stable version for which this doesn't happen?

ebkalderon · 2019-10-13T11:13:17Z

@jonas-schievink I'm checking the latest nightly right now, and I will report back back with my findings. I haven't tried this project with any older stable versions, but I'll try to roll back to 1.37.0 and see what happens.

jonas-schievink · 2019-10-13T11:23:21Z

Ah, it uses lexical-core, so this is a duplicate of #64705. Closing in favor of that, but thanks for filing anyways!

ebkalderon · 2019-10-13T11:27:51Z

@jonas-schievink Awesome, good to know I'm not the only one affected! With that said, the ICE still occurs on the latest 1.40.0-nightly but doesn't occur on 1.37.0. Running cargo doc --open at the workspace root, I get the following results:
