With the attached files the problem can be reproduced predictability:

Save the attached files b.h.master and b.h.next to a directory and cd to
it.

$ emacs -Q &
$ cp b.h.master b.h
C-x C-f b.h
$ cp b.h.next b.h
M-x revert-buffer

and the args-out-of-range error pops:

c-clear-char-property-with-value-function: Args out of range: 166, 453

I was unable to try with the latest Emacs sources because the build is
broken. My Emacs is from the 16 September.
