Package: cc-mode I run cc-mode with c parse state debugging turned on. In the course of normal usage, I found a file that reliably triggers a cache state inconsistency. (This is a courtesy report. I'm not actually encountering any bad cc-mode behavior right now.) Reproducer: emacs -Q C-x C-f test.h RET M-x c-toggle-parse-state-cache RET M-x what-line C-v M-x what-line The resulting log in *Messages*: c-debug-parse-state enabled Line 1 c-parse-state inconsistency at 2465: using cache: (2462 (1208 . 1674)), from scratch: (2462 (1863 . 2060)).
