Crashing (possibly while editing markdown)

Context of the crash:

I was editing some markdown containing haskell, while also having pretty big haskell files open.

I can’t provide the coredump as it contains confidential information, but let me know if there’s anything I can get out of it that would be useful to debug.

I just ran :TSUpdate, so I should be on the latest version of the parser. nvim-treesitter was version 9069849, and my nvim is this:

:ver
NVIM v0.7.0
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/02z6kwgc1ma1ra9ir2x1mnvm3qlz8s6l-neovim-unwrapped-0.7.0/share/nvim"

Run :checkhealth for more info

hey @414owen, what’s the reason for this being an assert?

  assert(to_copy <= TREE_SITTER_SERIALIZATION_BUFFER_SIZE);

I’d say there’s a good chance that’s what you’re hitting here, @lf-

and also
