objdump is part of the GNU binutils package.  Therefore I deduce from
this that you must be upgrading binutils from 7 to 9.  HOWEVER!  The
latest version of binutils appears to be 2.34 and therefore that does
not make sense.

  $ objdump --version

What is it exactly that you are trying to upgrade from 7 to 9?

Whatever that *thing* is that is where you should be directing your
questions.  But version 7 and version 9 do not match up with any
available version of binutils.

I have no idea what "brew cask" might possibly be.  Must be some Apple
thing?  Perhaps you should be discussing this problem with the people
behind that project?

I have no idea.

I have no idea.

Or at least the program did not report an error.

It all depends upon what else is running consuming memory at the same
time.  The program is reporting it is out of memory.  That's all I can
tell from the error message.

Generally these things tend not to be bugs in the upstream project
like binutils.  Since binutils is used by almost everything.
Typically I would expect to find this as a bug in the Apple Mac side
of things.  But that is just my experience.  I would go to the Apple
Mac side of things and open a discussion there about the problem.

However if you want to open a discussion with the binutils project
people then I would go to their project page.  I would see that they
list several resources for these things.

  https://www.gnu.org/software/binutils/

  Bug reports
  There is a bug-tracking system at http://sourceware.org/bugzilla/.

  Mailing lists
  There are three binutils mailing lists:

  bug-binutils@gnu.org
    For reporting bugs.

  binutils@sourceware.org
    For discussing binutils issues.

I would start by discussion.  Therefore I would send a mail message to
their sourceware address.  That is where the documentation is
directing people to go for discussion.  That is the place to start.  I
think it is unlikely to be a bug in binutils.

When doing this I would find the version of the software on your
system by running the utility with the --version option as I did
above.  Report that version information.

  $ objdump --version

Good luck!
