I am seeing a segfault running the libcephfs gtest suite. It's pretty rare (couple times a day running the test suite in a loop), and doesn't occur in the same test. I was able to get a core dump and backtrace. Hope this is helpful: Core was generated by `/home/nwatkins/projects/ceph/ceph/src/.libs/lt-test_libcephfs'.
