rust-analyzer: call to unsafe function ... on println! in minimal hello world app

[yanshay]

I have installed stable-aarch64-apple-darwin (active, default), rustc 1.90.0 (1159e78c4 2025-09-14), rust-analyzer 1.90.0 (1159e78c 2025-09-14).
I'm using nvim (lazyvim).

In my editor, I get strange errors from rust-analyzer, most notably on println! I get rust-analyzer: call to unsafe function is unsafe ....

I searched and found issue #20051 but it seems to have been taken care of long time ago and closed.

If I switch to another old toolchain I have on my system (so set it as default) things seems to function properly. (in 1.83-aarch64-apple-darwin).

How can I fix that?

That issue should have been fixed in your version. I guess you might be using other rust-analyzer version from other source (like mason.nvim) inside your editor

And when I switch a toolchain and it works it's because it's compatible with that rust version?

Yeah, the older version with your mason works well with the old toolchains

Ok, updated using Mason and indeed it seem to have fixed it.
Thanks!
