Clippy panic while getting the span of repr(transparent)

[mathisbot]

Summary

Clippy now panics when trying to find the span of a #[repr(transparent)] attribute.

This error is consistent and happens both on my Windows computer and in my GitHub CI (Linux) (cf. 1, 2, 3 and 4).

Here is the faulty line if needed in the whole file, or here is the related code:

#[repr(transparent)]
pub struct Link<T> {
    next: AtomicPtr<T>,
    _pin: core::marker::PhantomPinned,
}

Also note that clippy succeeded on rustc 1.87.0-nightly (46420c960 2025-02-22) and before.

Looks like the same issue as rust-lang/rust#137640 and has the same backtrace, so closing this one as a duplicate in favor of the one in the rust repo.
