--- Comment #1 from Alan Modra <amodra at gmail dot com> ---
A fuzzed core file with a section requiring an allocation of 43G will on most
systems cause you to run out of memory.  This isn't interesting at all.

The allocation of physical memory happens here in bfd_get_section_contents:
  if ((section->flags & SEC_HAS_CONTENTS) == 0)
    {
      memset (location, 0, (size_t) count);
      return TRUE;
    }

The binutils project should not be wasting time on this sort of non-bug.
