            Bug ID: 1304105
           Summary: glusterfs client crash when an entry is invalidated
           Product: GlusterFS
           Version: mainline
         Component: fuse
          Assignee: bugs at gluster.org

Description of problem:

glusterfs client segfaults when an entry is invalidated via setfattr interface.
This is the backtrace of the core generated.

warning: .dynamic section for "/usr/local/lib/libglusterfs.so.0" is not at the
expected address (wrong library or version mismatch?)
[Thread debugging using libthread_db enabled]
Using host libthread_db library "/lib64/libthread_db.so.1".
Core was generated by `/usr/local/sbin/glusterfs --volfile-server=hal9000
--volfile-id=mirror /mnt/glu'.
Program terminated with signal SIGSEGV, Segmentation fault.
