[Message part 1 (text/plain, inline)]

From emacs -Q, load the attached file.  Then use the following recipe to
trigger the error:

  M-x goto-line RET 334 RET
  TAB

After the tab, I get the error:

  c-just-after-func-arglist-p: Wrong type argument: integer-or-marker-p, nil

The backtrace is:

Debugger entered--Lisp error: (wrong-type-argument integer-or-marker-p nil)
