Code

This happens when compiling imgui crate. I have no minimal sample, really sorry about that. Happens in nightly-2024-12-06-x86_64-unknown-linux-gnu, but not in nightly-2024-12-05-x86_64-unknown-linux-gnu. Cross-compiling to windows via x86_64-pc-windows-msvc in release mode.

    Does this still crash on the latest nightly? The relevant code has been changed recently.

    cc @Urgau I'm pretty sure the root cause is this line:

    rust/compiler/rustc_lint/src/types.rs

    Line 490 in d185062

    format!(" as {fn_sig}")

    Doing formatting eagerly like this anywhere in the compiler is usually a time bomb, because if formatting happens then is ignored, there's a mechanism you can see in the backtraces to ensure that the compiler crashes.
