Happens in emacs -Q (after loading some simple elisp code that uses treesit.el) and consistently and repeatedly.


Here's the elisp. When I edebug it I can step and view all the variables and expressions I like. The `combobulate-' functions are widely used in the library and pose no issues anywhere else and do nothing more than fetch nodes via tree sitter. It is only this bit of code that blows up, and then only when invoked inside a python string.



    (when-let ((navigable-node (combobulate--get-nearest-navigable-node)) ;; <-- edebugging these work fine;
                 (nearest-node (combobulate-node-at-point))
                 (targets (seq-filter
                           (lambda (elem) (and elem (< elem (point))))
                           (list (save-excursion (ignore-errors (backward-up-list 1 t t) (point)))
                                 (combobulate-node-point (combobulate--nav-get-parent navigable-node)) ;; <- call into this inner form blows up when I read the argument value of `navigable-node' on the inside.
                                 (combobulate-node-point (combobulate--nav-get-parent nearest-node))))))
        (when-let (target (apply #'max targets))
          (goto-char target)
          (combobulate--flash-node (combobulate--get-nearest-navigable-node))))

Here is the "fix"

    (when-let* ((navigable-node (combobulate--get-nearest-navigable-node))
                      (nearest-node (combobulate-node-at-point))
                      (navigable-node-parent (combobulate--nav-get-parent navigable-node))  ;; <- refactor out 
                      (nearest-node-parent (combobulate--nav-get-parent nearest-node)) ;; <- refactor out
                      (targets (seq-filter
                                (lambda (elem) (and elem (< elem (point))))
                                (list (save-excursion (ignore-errors (backward-up-list 1 t t) (point))) ; <- smoking gun
                                      (combobulate-node-point navigable-node-parent)
                                      (combobulate-node-point nearest-node-parent)))))
            (when-let (target (apply #'max targets))
              (goto-char target)
              (combobulate--flash-node (combobulate--get-nearest-navigable-node))))

Clearly, `ignore-errors' + `backward-up-list' which throws errors left and right if it doesn't like what it's seeing is causing this.

If I instead of edebugging just run the code, it hangs Emacs. I have to kill -9 it.


Core dump's half a gig; not going to attach it.
