I'm also getting this error on Linux, while compiling a Bevy project that depends on bevy-inspector-egui = "0.21", with Rust 1.74 and opt-level = 3

[jakobhellermann]

I'll try to make a more minimal reproduction later and bisect rustc and submit a bug report for this (unless somebody wants to beat me to it)

[jakobhellermann]

Something pretty weird is going on, I can reproduce this when explicitly depending on the crates.io version.

Compiling in the repo or depending on it via path works fine.

Also in beta and nightly this issue doesn't seem to exist anymore if anyone needs a workaround.

[jakobhellermann]

regression was in rust-lang/rust@c545019 (rust-lang/rust#115759)

[jakobhellermann]

rust-lang/rust#117976

[jakobhellermann]

the issue is marked as regression-from-stable-to-stable and I-prioritize so it's maybe gonna get a backport into 1.74.1

[valyagolev]

for reference of whoever finds this:

[profile.release.package."bevy-inspector-egui"]
        opt-level = 1

works as a workaround

[rparrett]

Rust 1.74.1 was released. rustup update seems to have resolved the issue for me. Can anyone confirm?

[poperigby]

Can confirm that 1.74.1 fixed the issue.

[muhuk]

I can also confirm it is fixed with 1.74.1.

[Retrodad0001]

I can also confirm it is fixed with 1.74.1.
