--- Comment #3 from Worker Ant <bugzilla-bot at gluster.org> ---
COMMIT: https://review.gluster.org/20461 committed in master by "Atin
Mukherjee" <amukherj at redhat.com> with a commit message- glusterd: Fix glusterd
crash

Problem: gluster get-state command is crashing glusterd process, when
geo-replication session is configured.

Cause: Crash is happening due to the double free of memory. In
glusterd_print_gsync_status_by_vol we are calling dict_unref(), which
will free all the keys and values in the dictionary. Before calling
dict_unref(), glusterd_print_gsync_status_by_vol is calling 
glusterd_print_gsync_status(). glusterd_print_gsync_status is freeing
up values in the dictionary and again when dict_unref() is called, it
tries to free up the values which are already freed.

Solution: Remove the code which will free the memory in
glusterd_print_gsync_status function.

Fixes: bz#1598345
