Hi, I found a null pointer dereference bug in the source code of binutils, and
I have shown the execution sequence below. This bug exists in the file

Variable htab receives the return value from elf_x86_hash_table(which may be
null),and dereference without checking it is null or not.The detailed
instrunctions are in the attachment.
