When loading atsamd-rs BSPs, rust-analyzer crashes.
I don't have the VSCode Rust extension installed.

Steps to reproduce:

  1. VSCode Version 1.15.1
  2. Rust-Analyzer Version 0.2.408
  3. git clone https://github.com/atsamd-rs/atsamd.git
  4. code atsamd/boards/itsybitsy_m4

settings.json:

{
    "rust-analyzer.procMacro.enable": true,
    "rust-analyzer.cargo.loadOutDirsFromCheck": true,
    "window.zoomLevel": 0,
    "explorer.confirmDragAndDrop": false,
    "workbench.tree.indent": 24,
    "workbench.tree.renderIndentGuides": "always",
    "rust-analyzer.checkOnSave.command": "clippy",
    "files.eol": "\r\n",
    "editor.formatOnSave": true,
    "editor.defaultFormatter": "matklad.rust-analyzer",
    "rust-analyzer.updates.channel": "nightly",
    "rust-analyzer.checkOnSave.allTargets": false,
}

@Sympatron I am using vim and Coc.vim together with rust-analyzer. I can reproduce crash in my workspace with a different project. ( I used maud crate which heavily depends on proc-macro).

My Coc Setup

{
    "rust-analyzer.cargo.loadOutDirsFromCheck": true,
    "rust-analyzer.procMacro.enable": true,
    // comment  "rust-analyzer.diagnostics.disabled": [ "macro-error", "unresolved-proc-macro" ],
    "rust-analyzer.updates.channel": "nightly"
}

I use nvim + Coc.vim and after update to rust-analyzer-mac with version: dbd0cfb have proc macro server crashed. Before update all was fine. I don't remember previous version, but it is ~1month old.

The original crash in this issue is fixed. We can track further ones with no error messages under #6880.

seems I've hit similar problem again, (I've seen heap-use-after-free error in neovim lsp.log, but didn't save it, can not confirm if the heap-use-after-free error is triggered by rust-analyzer).

I'm using neovim builtin lsp
rust-analyzer 71117e6 2021-06-01 nightly

@comicfans that's related to #8925, #8928, #8929 and #9047 (comment) (not sure we need three issues for it, though).

You can either:

  • use an older nightly
  • disable proc macros
  • use a stable toolchain

We won't be able to merge any fix soon, unfortunately.
