Unable to fetch cargo metadata with enabled parallel frontend on 1.76.0-nightly (9fad68599 2023-12-03)

[Gordon-F]

I tried this code:

1. Download source https://github.com/NiklasEi/bevy_game_template/tree/5f7dbc2b1fccd3fbc6b6c08eed9b82f6b9a57985
2. Add cargo config:

[target.x86_64-unknown-linux-gnu]
linker = "clang"
rustflags = [
    "-Clink-arg=-fuse-ld=mold",
    "-Zshare-generics=y",
    "-Zthreads=8"]

[target.x86_64-apple-darwin]
rustflags = [
    "-C",
    "link-arg=-fuse-ld=/usr/local/opt/llvm/bin/ld64.lld",
    "-Zshare-generics=y",
    "-Zthreads=8"
]

[target.aarch64-apple-darwin]
rustflags = [
    "-C",
    "link-arg=-fuse-ld=/opt/homebrew/opt/llvm/bin/ld64.lld",
    "-Zshare-generics=y",
    "-Zthreads=8"
]

[target.x86_64-pc-windows-msvc]
linker = "rust-lld.exe"
rustflags = ["-Zshare-generics=n", "-Zthreads=8"]

3. Run cargo metadata --verbose --format-version 1 --all-features --filter-platform x86_64-unknown-linux-gnu

I expected to see this happen: metadata json

Instead, this happened: ICE

  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: please attach the file at `/home/devuser/Dev/RustProjects/bevy_game_template/rustc-ice-2023-12-04T10_43_06-21190.txt` to your bug report

  note: compiler flags: -C link-arg=-fuse-ld=mold -C link-arg=-fuse-ld=mold -Z share-generics=y -Z threads=8 --crate-type bin --crate-type rlib --crate-type dylib --crate-type cdylib --crate-type staticlib --crate-type proc-macro

If you comment out the parallel front end setting in config.tom, everything will work as expected:

[target.x86_64-unknown-linux-gnu]
linker = "clang"
rustflags = [
    "-Clink-arg=-fuse-ld=mold",
    "-Zshare-generics=y",
    #"-Zthreads=8"

Could this be #118588?

[Gordon-F]

@lqd Yes, thank you! It's look like the same issues
