PR 21813 binutils* rddbg.c (read_symbol_stabs_debugging_info): Check for an empty string whilst concatenating symbol names. bfd * mach-o.c (bfd_mach_o_canonicalize_relocs): Pass the base address of the relocs to the canonicalize_one_reloc routine. * mach-o.h (struct bfd_mach_o_backend_data): Update the prototype for the _bfd_mach_o_canonicalize_one_reloc field. * mach-o-arm.c (bfd_mach_o_arm_canonicalize_one_reloc): Add res_base parameter. Use to check for corrupt pair relocs. * mach-o-aarch64.c (bfd_mach_o_arm64_canonicalize_one_reloc): Likewise. * mach-o-i386.c (bfd_mach_o_i386_canonicalize_one_reloc): Likewise. * mach-o-x86-64.c (bfd_mach_o_x86_64_canonicalize_one_reloc): Likewise. * vms-alpha.c (_bfd_vms_slurp_eihd): Make sure that there is enough data in the record before attempting to parse it. (_bfd_vms_slurp_eeom): Likewise. (_bfd_vms_slurp_egsd): Check for an invalid section index. (image_set_ptr): Likewise.
