    More fixes for buffer overruns instigated by corrupt binaries.
    
    	PR binutils/17512

    	be read.
    	(dump_relocs_in_section): Likewise.

    	(slurp_reloc_table): Likewise.
    	* coffcode.h (coff_slurp_line_table): Remove unneeded local
    	'warned'.  Do not try to print the details of a symbol with an
    	invalid index.

    	index against length of string table.

    	against length of string table.

    	table in the coff_tdata structure.
    	(bfd_coff_free_symbols): Set the length of the string table to
    	zero when it is freed.
    	(coff_get_normalized_symtab): Check offsets against string table
    	or data table lengths as appropriate.

    	length of string table.
    	* compress.c (bfd_get_full_section_contents): Check computed size
    	against the size of the file.
    	* libcoff-in.h (obj_coff_strings_len): Define.
    	(struct coff_tdata): Add strings_len field.
    	* libcoff.h: Regenerate.
    	* peXXigen.c (pe_print_debugdata): Do not attempt to print the
