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.

Inspect the resulting Python 2.7 segmentation fault and confirm completion when the attached crushmap is analyzed without crashing.
