the parser segfaults tree-sitter when opening a fairly large perl file (in neovim)

[nekopsykose]

opening inxi from https://github.com/smxi/inxi/commit/a5e8e3eec7796ea38679c8c3c8c5da0e53cd2d87 seems to cause a segfault in tree-sitter. not having the tree-sitter-perl parser installed via nvim-treesitter fixes that.

i'm not sure of the easiest way to reproduce it, but i can reproduce it with either git or latest (0.6.2) neovim, with nvim-treesitter installed as a plugin, and only the perl parser loaded. something like:

local execute = vim.api.nvim_command

require("plugins")
execute(":packloadall")

local ts_configs = require("nvim-treesitter.configs")

ts_configs.setup({
  ensure_installed = { "perl" },
  highlight = { enable = true, use_languagetree = true },
})

as .config/nvim/init.lua, and .config/nvim/lua/plugins.lua:

local execute = vim.api.nvim_command
local install_path = vim.fn.stdpath("data") .. "/site/pack/paqs/start/paq-nvim"

if vim.fn.empty(vim.fn.glob(install_path)) > 0 then
  execute("!git clone --depth 1 https://github.com/savq/paq-nvim " .. install_path)
  execute("packadd paq-nvim")
end

local packages = {
  -- highlighting
  {
    "nvim-treesitter/nvim-treesitter",
    run = function()
      execute(":TSUpdate")
    end,
  },
}

return require("paq")(packages)

from there, you could start neovim, run :PaqSync (you need a c compiler and git installed), then it /should/ install the parser after, if not, :TSUpdate/:TSInstall perl would sync that

then, opening the above inxi perl file causes a segfault from this parser. apologies, i don't know of another way to use the parser in a more minimal reproduction

[ptrcnull]

here's the smallest perl script i could reproduce this issue with:

{
package UsbData;
my (@working);
sub set {
    eval $start if $b_log;
    ${$_[0]} = 1; # set checked boolean
    # note: bsd package usbutils has lsusb in it, but we dont want it for default
}

# get driver, interface [type:] data
sub uevent_data {
    foreach (@files){
        last if $b_hub;
        # print "f2: $_\n";
        ($interface) = ('');
        @working = main::reader($_) if -r $_;
    }
    return @drivers;
}
}

unfortunately, i couldn't get it to segfault using py-tree-sitter, it might be specific to how nvim-treesitter calls the library

[ptrcnull]

ah, it segfaults with just this:

$ tree-sitter generate
$ tree-sitter parse repr.pl

[ganezdragon]

I haven't used neovim, so let me try it out and see if it segfaults.

[nekopsykose]

the repro didn't require using neovim, just the above steps worked.

nevertheless, i can't reproduce this anymore (even on the older version at the time..). fun :)
