--- Comment #2 from Alan Modra <amodra at gmail dot com> ---
I'm inclined to think that fuzzed binaries that cause huge memory allocations
are not something that the binutils project should be concerned about.  Your
binary says it has 3909091329 verneed entries, which on a 64-bit host are
stored internally in a 64 byte struct.  That's 250181845056 bytes.

On my system
bfd_zalloc2 (address@hidden, nmemb=3909091329, address@hidden)
fails with ENOMEM.

I think that is a quite reasonable result.

However, this particular case can be easily detected so I'll fix it
