Starting point to debug/fix this would be to extract the osdmap from
one of the dead OSDs:

ceph-objectstore-tool --op get-osdmap --data-path /var/lib/ceph/osd/...

Then try to run osdmaptool on that osdmap to see if it also crashes,
set some --debug options (don't know which one off the top of my
head).
Does it also crash? How does it differ from the map retrieved with
"ceph osd getmap"?

You can also set the osdmap with "--op set-osdmap", does it help to
set the osdmap retrieved by "ceph osd getmap"?
