objdump segfault after symbol table error
This memcpy segfaults if symcount is -1 (=> syms is NULL).
memcpy (sorted_syms, symcount ? syms : dynsyms,
sorted_symcount * sizeof (asymbol *));
* objdump.c (slurp_symtab): Don't leave symcount as -1 after
an error.
(slurp_dynamic_symtab): Likewise for dynsymcount.
