tracing::instrument causes rust-analyzer server to panic with "range end index out of range"

[tigercat2000]

rust-analyzer version: (eg. output of "Rust Analyzer: Show RA Version" command)
rust-analyzer version: 0.0.0 (5342f47 2022-07-09)

rustc version: (eg. output of rustc -V)
rustc 1.64.0-nightly (6dba4ed21 2022-07-09)

relevant settings: (eg. client settings, or environment variables like CARGO, RUSTUP_HOME or CARGO_HOME)
tracing 0.1.35
tracing-attributes 0.1.22
proc-macro2 1.0.40

This may be related to this issue, but I'm not sure: #12674

Using the proc-macro tracing::instrument will cause rust-analyzer to panic.
This results in textDocument/hover and textDocument/inlayHint to return []. However, textDocument/publishDiagnostics still works.

Minimal reproduction:
Cargo.toml

[package]
name = "rabug"
version = "0.1.0"
edition = "2021"
[dependencies.tracing]
version = "0.1.35"
features = ["attributes"]

main.rs

#[tracing::instrument]
fn one() {
    let should_have_inlay = 1u32;
}

fn main() {
    println!("Hello, world!");
}

This causes the following panic:

thread '<unnamed>' panicked at 'range end index 4 out of range for slice of length 0', library\core\src\slice\index.rs:73:5

Ahhh, thank you for pointing me to the original issue 😄
