COMMIT: http://review.gluster.org/13249 committed in release-3.7 by Pranith Kumar Karampuri (pkarampu@redhat.com)

    protocol/server: Fix memory corruption during client-table-expand.
    gf_client_clienttable_expand frees up old entries after expanding. So,
    cliententry should be reassigned to a free slot in new array of
    cliententries. Earlier it used to point to a slot in oldentries
    resulting in a use-after-free bug.
    Thanks to Pranith for the assistance provided.

Client crash was because of glibc issue tracked by bz 1027101 and bz 1305406.

This bug is getting closed because a release has been made available that should address the reported issue. In case the problem is still not fixed with glusterfs-3.7.7, please open a new bug report.

glusterfs-3.7.7 has been announced on the Gluster mailinglists [1], packages for several distributions should become available in the near future. Keep an eye on the Gluster Users mailinglist [2] and the update infrastructure for your distribution.
