LSP-clangd repeatedly crash after loading pytorch source code #4422

Thank you for the bug report

Bug description

After build pytorch with option USE_CUDA=0 and USE_CUDNN=0, I load the source code into emacs and found the clangd repeatedly crash during code navigation. The screenshot is: image

The stack(filtered) print in the lsp stderr is:

I close this issue:

  1. Investigation revealed the crash originated from Clangd, not the LSP client. The stack trace confirmed this.
  2. The installed Clangd version was outdated (version 12.0). Upgrading to the latest version (18.x.x) resolved the problem.
