    You will need to codesign the binary. For instructions, see:

      https://sourceware.org/gdb/wiki/BuildingOnDarwin

    On 10.12 (Sierra) or later with SIP, you need to run this:

      echo "set startup-with-shell off" >> ~/.gdbinit
  EOS
  end

  test do
    system bin/"gdb", bin/"gdb", "-configuration"
  end
end
