What is reproducible, exactly?
I don't understand. The infinite loop is reproducible, "pegging one
core" as he expressed it, using up one CPU core.
Visiting the file is almost
instantaneous here, in Emacs 29. What did you do to get Emacs into an
infloop?
Maybe I switched applications with Cmd-TAB, or something else triggering
redisplay. Do a M-x or C-l.
It is IMO unreasonable to expect CC Mode to do something sensible with
random sequence of characters that don't resemble C in any way.
I think no-one expects that. The bug is the uninterruptable loop or
whatever causes it.
