The problem was identified in handling of the zpool get state command line arguments. A pointer vdev was used to point to the argv[1], and its address set to cb.cb_vdevs.cb_names(pointer to array of strings) so any increment to cb_names resulted in a segfault. Fix covers a special case of root parameter at argv[1] and remaining cases are handled by passing in the argv + 1, which allows cb_names iteration of next command line arguments (vdevs).
