clangd crash on stdexec project

[BartolomeyKant]

I added stdexec to my project and clangd starts crashing if it goes through its symbols.

I figured out how to reproduce it without any of my code.

1. Clone stdexec repo https://github.com/NVIDIA/stdexec
2. Configure it with CMake. It has a clangd helper witch automatically add CMAKE_EXPORT_COMPILE_COMMANDS and create symlink to compile_commands.json into repo root directory. Ensure it is. It also provides .clangd config file.
3. Open project in editor with clangd. I'm using Zed with the following options

 "lsp": {
    "clangd": {
      "binary": {
        "arguments": [
          "--header-insertion=never",
          "--query-driver=**"
        ]
      }
    }
  }

But it looks like it does not depend on my options.
4. Open one of the files e.g examples/hello_coro.cpp
5. Try to modify the file and format it with cland's clang-format.
6. After a few seconds clangd is crashed with logs:

Details

I added stdexec to my project and clangd starts crashing if it goes through its symbols.

I figured out how to reproduce it without any of my code.

1. Clone stdexec repo https://github.com/NVIDIA/stdexec
2. Configure it with CMake. It has a clangd helper witch automatically add CMAKE_EXPORT_COMPILE_COMMANDS and create symlink to compile_commands.json into repo root directory. Ensure it is. It also provides .clangd config file.
3. Open project in editor with clangd. I'm using Zed with the following options

 "lsp": {
    "clangd": {
      "binary": {
        "arguments": [
          "--header-insertion=never",
          "--query-driver=**"
        ]
      }
    }
  }

But it looks like it does not depend on my options.
4. Open one of the files e.g examples/hello_coro.cpp
5. Try to modify the file and format it with cland's clang-format.
6. After a few seconds clangd is crashed with logs:

[HighCommander4]

Can the project be built successfully with clang as the compiler, with the version matching clangd's (i.e. 22.1.1)?

Can the project be built successfully with clang as the compiler, with the version matching clangd's (i.e. 22.1.1)?

yes, it can.

[HighCommander4]

Seems to be a regression in clangd 22, so a workaround until this is resolved is to use clangd 21.

[HighCommander4]

A good next step would be to reduce the crashing code to something more minimal.
