Thanks for the recipe. I turned on debug-on-error and got this
traceback:
Debugger entered--Lisp error: (args-out-of-range 166 453)
remove-text-properties(166 453 (category))
c-clear-char-property-with-value-function(1 453 category c-cpp-delimiter)
c-neutralize-syntax-in-and-mark-CPP(94 94 286)
c-after-change(94 94 286) <<======================================
insert-file-contents("/home/acm/b.h" t nil nil t)
revert-buffer(t)
call-interactively(revert-buffer nil nil)
c-after-change is on the after-change-functions hook. The values of BEG
END OLD-LEN it is being passed look utterly wrong. BEG and END should
delimit the entire buffer and OLD-LEN should be the length of the
previous buffer. Surely?
