I'm getting a new warning with gcc-7: isci/remote_node_context.c: In function 'sci_remote_node_context_destruct': isci/remote_node_context.c:69:16: error: array subscript is above array bounds [-Werror=array-bounds] This is odd, since we clearly cover all values for enum scis_sds_remote_node_context_states here. Anyway, checking for an array overflow can't harm and it makes the warning go away.
