If I understand correctly your use case (next_gw() called after
t_relay() error, always adding only 1 branch and called form
request_route) then yes:
if t!= T_UNDEFINED and t!=0 and t->nr_of_outgoings!=0 =>
    uri "consumed", add branch,
else if t==0 or UNDEFINED =>
    exit with error (something bad has happend, probably out-of-mem)
else
    uri was bad => change ruri.
