30.0.50; Errors during redisplay with c++-ts-mode |

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

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

Thanks, installed on master, and closing the bug.
