> Before we continue, let me note that this seems like another case where tree-sitter-c parser chokes on some extreme C code. Profiler reports shows that almost all time are spent in treesit-parser-root-node, which indicates that all the time are spent parsing the text.

So maybe this is something to report to tree-sitter and/or
tree-sitter-c developers?  (Does c++-ts-mode behave better with this
file?)
