+++ This bug was initially created as a clone of Bug #1490897 +++

Description of problem:

glusterd_get_args_from_dict() creates a new dict from unserialization of the
data coming from getspec. From there it extracts 'brick_name' and stores the
pointer to argument brick_name (a char **). Just before returning, dict is
released, deallocating all related data, including the string pointer by
brick_name.

Version-Release number of selected component (if applicable): mainline
