  To: 28850, acm

This bug is bugging me for quite some time now, and my hopes for it to
be resolved are now gone, so I finally sat down to debug it.

I have jit-lock-stealth turned on in my sessions, so whenever I
restart Emacs (e.g., when I build a new binary, or after a system
restart), and restore my session using desktop.el, Emacs starts
fontifying in the background.  At some point, sometimes more than
once, I get this error:

  Error running timer 'jit-lock-stealth-fontify': (error "Invalid search bound (wrong side of point)")

Today I ran Emacs under a debugger, and caught this error.  The
details are below, but in a nutshell, CC mode's fontification
functions call re-search-forward with BOUND that is before point.  I
hope the data below is enough to understand why that happens and fix
it; if not, please tell what additional data is needed to diagnose the
problem.

Here're the C and Lisp backtraces from the error, and some relevant
data that explains why the error happened:

So point is 123811 and the BOUND argument of re-search-forward is
123806, too small.

  (gdb) p current_buffer
  $4 = (struct buffer *) 0xb362590
  (gdb) pp current_buffer->name_
  "process.c"

These are the regexp argument to re-search-forward and the buffer
which was being fontified.

The problem happens in c-syntactic-re-search-forward in this snippet:

    (condition-case err
	(while
	    (and
	     (progn
	       (setq search-pos (point))
	       (if (re-search-forward regexp bound noerror)  <<<<<<<<<<<
		   t
		 ;; Without the following, when PAREN-LEVEL is non-nil, and
		 ;; NOERROR is not nil or t, and the very first search above
		 ;; has just failed, point would end up at BOUND rather than
		 ;; just before the next close paren.
		 (when (and (eq search-pos start)
			    paren-level
			    (not (memq noerror '(nil t))))
		   (setq state (parse-partial-sexp start bound -1))
		   (if (eq (car state) -1)
		       (setq bound (1- (point)))))
		 nil))

This is called from c-forward-declarator:

	 ;; Search syntactically to the end of the declarator (";",
	 ;; ",", a closing paren, eob etc) or to the beginning of an
	 ;; initializer or function prototype ("=" or "\\s\(").
	 ;; Note that square brackets are now not also treated as
	 ;; initializers, since this broke when there were also
	 ;; initializing brace lists.
	 (let (found)
	   (while
	       (and (progn
		      ;; In the next loop, we keep searching forward whilst
		      ;; we find ":"s which aren't single colons inside C++
		      ;; "for" statements.
		      (while
			  (and
			   (setq found
				 (c-syntactic-re-search-forward   <<<<<<<<<<<
				  "[;:,]\\|\\s)\\|\\(=\\|\\s(\\)"
				  limit t t))


It looks like c-syntactic-re-search-forward calls re-search-forward in
a loop, but perhaps it fails to update the limit to be in sync with
point that moves as the search proceeds?

Let me know what other data I can provide to help fix this annoying
problem.
