Ceph

For example:

root@noisy:/var/lib/ceph/mon.noisy/monmap# monmaptool --print latest 
monmaptool: monmap file latest
terminate called after throwing an instance of 'std::bad_alloc'
  what():  std::bad_alloc
Aborted
root@noisy:/var/lib/ceph/mon.noisy/monmap# monmaptool --print /root/.bashrc 
monmaptool: monmap file /root/.bashrc
terminate called after throwing an instance of 'ceph::buffer::end_of_buffer'
  what():  buffer::end_of_buffer
Aborted
root@noisy:/var/lib/ceph/mon.noisy/monmap#

It should exit with a non-zero exit status and a nice message when the input is not a monmap.
