Segfault after modifying CRUSHMAP: NOTE: a copy of the executable, or `objdump -rdS <executable>` is needed to interpret this.

Hi guys,

I was creating new buckets and moving buckets around when 1 monitor 
stopped replying.

The scenario is:
2 servers
2 MONs
21 OSDs each server

I uploaded the stderr to:
http://ur1.ca/jxbrp

when I try to run:
/usr/bin/ceph-mon -i zrh-srv-m-cph01 --pid-file 
/var/run/ceph/mon.zrh-srv-m-cph01.pid -c /etc/ceph/ceph.conf --cluster 
ceph -d

On the other Mon, trough the admin_socket I get:
# ceph --admin-daemon /var/run/ceph/ceph-mon.rml-srv-m-cph01.asok 
quorum_status

            { "rank": 1,

              "addr": "192.168.0.20:6789\/0"}]}}
