Not any more.

If tree-sitter really needs a deep stack whose size depend on the input file and grammar in an unbounded way, then it shouldn't use the C stack; that would be an unnecessary restriction on the files that could be edited. A dynamically allocated stack could still have a limit, but it would be decoupled from the C stack size.
