this seems compiler problem. could you try to build it with “lto=off”

[Andrey Voronkov]

Tried both cargo build and cargo build --release with these settings in Cargo.toml:

[profile.dev]
lto = "off"

[profile.release]
codegen-units = 1
lto = "off"
panic = "abort"

and getting the exact same error. Did I turned off lto correctly?

[Nikolay Kim]

try 1.65,1.66 rust version. and probably report it to rust

[Nikolay Kim]

lets keep it open for now. if you create issue in rust repo could you reference this one

[Andrey Voronkov]

@fafhrd91 Sure

[Nikolay Kim]

seems fixed in latest rustc
