Then it's strange, since it doesn't happen here.  Does it happen for
you with any C source file, including those in the Emacs source tree?
If this happens only for some files, can you post one such file?

Also, what version of the tree-sitter library are you using, and what
version of the C grammar library?

If you can build the emacs-29 branch, can you try reproducing there?

Yuan, any ideas, based on the backtrace?
