rust-analyzer panic when call `callHierarchy/outgoingCalls`

[eval-exec]

rust-analyzer version: (eg. output of "rust-analyzer: Show RA Version" command, accessible in VSCode via Ctrl/⌘+Shift+P) 1.81.0-nightly (9c3bc80 2024-06-27) rustc version: (eg. output of rustc -V)

rustc 1.81.0-nightly (9c3bc805d 2024-06-27)
binary: rustc
commit-hash: 9c3bc805dd9cb84019c124b9a50fdff1e62a7ec9
commit-date: 2024-06-27
host: x86_64-unknown-linux-gnu
release: 1.81.0-nightly
LLVM version: 18.1.7

editor or extension: (eg. VSCode, Vim, Emacs, etc. For VSCode users, specify your extension version; for users of other editors, provide the distribution if applicable) Emacs with lsp-mode.el relevant settings: (eg. client settings, or environment variables like CARGO, RUSTC, RUSTUP_HOME or CARGO_HOME)

repository link (if public, optional): (eg. rust-analyzer) https://github.com/BurntSushi/ripgrep/blob/master/crates/core/messages.rs#L124

code snippet to reproduce:

1. Put cursor on https://github.com/BurntSushi/ripgrep/blob/master/crates/core/messages.rs#L124
2. call callHierarchy/outgoingCalls will got the panci:

Can't reproduce with a recent version and VS Code, can you try using https://github.com/rust-lang/rust-analyzer/releases/download/nightly/rust-analyzer-x86_64-unknown-linux-gnu.gz instead of the rustup component?

Can't reproduce with a recent version and VS Code, can you try using https://github.com/rust-lang/rust-analyzer/releases/download/nightly/rust-analyzer-x86_64-unknown-linux-gnu.gz instead of the rustup component?

After you call callHierarchy/outgoingCalls, you can try expand the child nodes.

[eval-exec]

Can you reproduce, if you put cursor on /home/exec/.rustup/toolchains/nightly-x86_64-unknown-linux-gnu/lib/rustlib/src/rust/library/core/src/sync/atomic.rs:3295 (put cursor on atomic_store) then call callHierarchy/outgoingCalls ?

Looks like ~/.rustup/toolchains/nightly-x86_64-unknown-linux-gnu/lib/rustlib/src/rust/library/core/src/sync/atomic.rs has some smart quotes at line 31, can you check if you're running a recent version of lsp-mode?

Or can you try replace those quotes, then restart? Cf.
