Doesn't repro on linux/x64. I'll try on darwin/arm64 next.

sandersn commented 2 months ago

It doesn't repro on darwin/arm64 either. Admittedly I have an M1 with 16 GB of memory. Does it reproduce if you shut off all the other extensions?

Edit: Tried on both 1.92 and 1.93-insider, on mac.

nnmrts commented 2 months ago

Interesting, might be the deno extension. Now that I actually have time to purposely crash my machine repeatedly, I'll try it out. See you on the other side. ;)

nnmrts commented 2 months ago

Yep, it's the deno extension or rather just deno. New minimal repro:

  1. Install the deno extension.
  2. Create .vscode/settings.json 
    {
    "deno.enable": true
}

  3. Create test.js

    /**
 * @import random from "/dev/random";
 */

/**
 * @typedef {`${random}`} Test
 */
  4. Now hover over Test and watch your CPU and memory melting until everything freezes and/or crashes.

I reported this at https://github.com/denoland/vscode_deno/issues/1158.
