Failed to install wasmi_cli: raw mutable pointers are not allowed in statics (Rust 1.77.1)

I tried to run cargo install wasmi_cli to test this lib but got the following:

error[E0658]: raw mutable pointers are not allowed in statics

Whlith which Rust compiler version did you try.to install Wasmi? I have never seen this error before during development. Maybe Wasmi CI should be extended to cover certain missing specs.

After some testing this seems to be linked to rustc version

By default I was using rustc 1.77.1 (7cf61ebde 2024-03-27) (gentoo) but upgrading to 1.79.0 allowed me to compile wasmi_cli successfully

Thanks a lot for the response and the bug report. I will have to see why this occurs in v1.77.1 to eventually close this issue.

Failure in Rust 1.77.1 (and previous versions) occurs while Rust 1.78 compiles fine is due to this change:
rust-lang/rust#117614

I was not aware how new this change actually was.
Since Wasmi is pinned to Rust 1.77 we probably want to address this to keep Wasmi compilable with Rust 1.77.
