When listing symbols in a lib file, it crashed here.

Here is the code, the sym variable got a value as 1,
/* FIXME: We should not be casting between ints and
pointers like this. */
sym = ((coff_symbol_type *)
((symndx + obj_raw_syments (abfd))
->u.syment._n._n_n._n_zeroes));
then it crashed at
if (sym->lineno != NULL && ! warned)
I'm proposing a solution as below, to check the sym after setting its value.
//brook
if(sym < obj_symbols (abfd) ) {
_bfd_error_handler (_("%B: warning: illegal symbol address %x,
which should be greater than %x"),
abfd, sym, obj_symbols (abfd));
continue;
}
