commit 201159ecec7e17600df4153e5d4e7a145f0c7cfe
Author: Nick Clifton <address@hidden>
Date:   Tue Nov 11 15:34:27 2014 +0000

    More fixes for invalid memory accesses, uncovered by valgrind and binary
fuzzers.

        PR binutils/17512
        * coffcode.h (coff_slurp_line_table): Initialise the parts of the
        line number cache that would not be initialised by the copy from
        the new line number table.
        (coff_classify_symbol): Allow for _bfd_coff_internal_syment_name
        returning NULL.
        * coffgen.c (coff_get_normalized_symbols): Get the external
        symbols before allocating space for the internal symbols, in case
        the get fails.
        * elf.c (_bfd_elf_slurp_version_tables): Only allocate a verref
        array if one is needed.  Likewise with the verdef array.
        * peXXigen.c (_bfd_XXi_swap_sym_in): Replace abort()'s with error
        messages.
        (_bfd_XXi_swap_aux_in): Make sure that all fields of the aux
        structure are initialised.
        (pe_print_edata): Avoid reading off the end of the data buffer.
