Description

I have a ceph cluster.
Use "ceph osd crush dump > map.json" to get the crushmap about my ceph cluster.
And then, run "crush analyze --rule replicated --crushmap map.json", it occurs a segmentation fault.
The log display in dmesg is "[12471.824472] crush[27369]: segfault at ffffffffffffffff ip 00000000004539b9 sp 00007ffe8a036370 error 5 in python2.7[400000+2bb000]".

Do you have some comments about this? If you have, i will appreciate you very much.
The attached file is the crushmap file about the ceph cluster.
