That file opens just fine in other modesIt also opens fine in c-mode, with global-font-lock-mode disabled.
Indeed, obviously it's a c-mode font-locking related bug.
Note that this bug has nothing to do with long lines.I imagine that the font-lock issue is related to the line being in excess of 21,000 chars (but general redisplay obviously doesn't have problems with lines this 'small').Reduced to 10,208 chars that file opens instantly under emacs -Q in c-mode with font-lock enabled; but at 10,209 chars it hangs Emacs (I killed it after waiting 4 minutes).
Interesting, thanks for the bisection!
