elf_read_notes in master binutils uses _bfd_malloc_and_read, and that function
checks any memory allocation against file size. I can't spot any bugs there or
in the function that returns file size, even if you were building 32-bit x86
binaries. From your crash message it looks like "size" must be a 64-bit x64_64
binary.
I think, like Nick, that you are fuzzing an older version of binutils.
