It's this line in xgetsysm:
set $ptr = ((struct Lisp_Symbol *) ((char *)lispsym + $ptr))
where $ptr is a pointer to a Lisp_Symbol object:
(gdb) p $ptr
$2 = (struct Lisp_Symbol *) 0x17c9e38 <dumped_data+267384>
and lispsym is an array:
(gdb) ptype lispsym
type = struct {
struct Lisp_Symbol s;
} [1298]
Let me know if I can provide more information about this.
