Emacs: 6f2036243f2 (2024-06-23, latest master)
Tree-sitter: 3da7deed (2024-06-08, version 0.22.6)
The immediate cause of the crash is that tree-sitter accessed a node's
tree, but the tree is already deleted. Commenting out the
ts_tree_delete line in treesit_ensure_parsed can "fix" the crash.
What happended, I think, is this:
1. Buffer modified, parser->need_reparse set to true,
parser->timestamp incremented.
2. A node is created from the parser, this node has the old tree but
the new timestamp (bad!).
3. Parser re-parses (treesit_ensure_parsed), new tree created, old
tree deleted.
4. Ftreesit_query_capture accessed the old node, and the old tree,
crash.
We shouldn't bump the parser timestamp when we set
parser->need_reparse to true; instead, we should bump the timestamp
when we actually reparsed and created a new tree.
