I'm using clangd 19.1.0 through neovim and experiencing regular crashes. As requested by the error message, I am reporting the bug here. Below is the error and stack trace as they appear in my `~/.local/state/nvim/lsp.log`. I believe this is reproduceable on [this tag of the PX4 repository.](https://github.com/PX4/PX4-Autopilot/tree/v1.13.3). Crashing happens on a variety of files after doing a few "go to definition" commands or similar LSP actions.
After reading [How to submit an LLVM bug report](https://llvm.org/docs/HowToSubmitABug.html), I'm not sure what other information I should include. Please let me know if I can provide anything else.
