Subject: 30.0.50; Errors during redisplay with c++-ts-mode
Date: Wed, 12 Jun 2024 15:33:17 +0300

To reproduce in "emacs -Q", visit some C++ source file (I used
breakpoint.c from the GDB sources), then turn on c++-ts-mode.  The
fontification is all incorrect, and *Messages* has these error
messages:

  Error during redisplay: (jit-lock-function 7286) signaled (treesit-query-error "Node type error at" 575 "[\"_Atomic\" \"break\" \"case\" \"const\" \"continue\" \"default\" \"do\" \"else\" \"enum\" \"extern\" \"for\" \"goto\" \"if\" \"inline\" \"register\" \"restrict\" \"return\" \"sizeof\" \"static\" \"struct\" \"switch\" \"typedef\" \"union\" \"volatile\" \"while\" \"and\" \"and_eq\" \"bitand\" \"bitor\" \"catch\" \"class\" \"co_await\" \"co_return\" \"co_yield\" \"compl\" \"concept\" \"consteval\" \"constexpr\" \"constinit\" \"decltype\" \"delete\" \"explicit\" \"final\" \"friend\" \"mutable\" \"namespace\" \"new\" \"noexcept\" \"not\" \"not_eq\" \"operator\" \"or\" \"or_eq\" \"override\" \"private\" \"protected\" \"public\" \"requires\" \"template\" \"throw\" \"try\" \"typename\" \"using\" \"virtual\" \"xor\" \"xor_eq\"] @font-lock-keyword-face (auto) @font-lock-keyword-face (this) @font-lock-keyword-face" "Debug the query with `treesit-query-validate'")

This happens with the latest C++ tree-sitter grammar library.  I guess
they made some incompatible change in the grammar or something?
