Opening specific files causes freeze

[afreakk]

Im using this treesitter for neovim, and its been fine until I tried opening:
pkgs/development/haskell-modules/make-package-set.nix from nixpkgs.

Then neovim froze and started using enourmous amounts of memory until I killed neovim.
This happens every time I open that file using neovim with this treesitter, if I disable the nix treesitter parser it opens fine.
Not sure how to debug this, so this is not very helpfull, but I could easily reproduce the issue atleast.

 ❯ nvim --version
NVIM v0.8.2
Build type: Release
LuaJIT 2.1.0-beta3
Compiled by nixbld

Features: +acl +iconv +tui
See ":help feature-compile"

   system vimrc file: "$VIM/sysinit.vim"
  fall-back for $VIM: "
/nix/store/dl03s9vbm0i0qqg6sqv37rvd4mghbk6c-neovim-unwrapped-0.8.2/share/nvim
"

Same issue on Neovim, with the following minimal nix file:

{}: let
in {
  programs.waybar = {
  exec = let
  in
    pkgs.writeShellScript "todo-waybar" ''
      $(${todo} | ${wc} -l)
    '';
  };
}

Seems to be caused by the bash parser, byt the injection at line 7, the |

Hmm. That's no good. Thanks for the report!

I'm super swamped at the moment, so if anyone can take a stab at debugging this, it would be greatly appreciated. Otherwise I'll take a look as soon as I have some spare time.

Treesitter has fixed a bug upstream that at least fixed the issue from my minimal nix file.

Thats weird, it didnt for me, running nvim-treesitter (0e6d4b4), and disabled all my treesitter plugins like nvim-hop and matchup.
Will try a minimal nvim config later with only treesitter and nothing else installed

A more minimal example

writeShellScript "test" "$(${x}|${y} )"

writeShellScript ( queries/injections.scm:17 ) turns the following string to be:

 (#set! injection.language "bash")
 (#set! injection.combined))

So when I tried removing my bash treesitter parser, it didnt freeze anymore.

The treesitter dep was updated in a very recent nightly Neovim built.

See here: neovim/neovim#21858

I'm fairly certain that this has been resolved upstream, so I'll close this now; if I'm mistaken, ping me and I'll reopen.
