In the loop head node, references [i15] were interesting.
By SMT, we could prove
((0 <= initial_i15 and 0 <= initial_i1) and (((path1_i22 = (path1_i15 * path1_i15) and path1_i22 = path1_i26 and path1_i30 = (path1_i15 + 1) and path1_i30 = res_i15 and path1_i1 = res_i1 and path1_i15 = initial_i15 and path1_i1 = initial_i1) and (path1_i26 > 9 and path1_i15 >= 0)) and ((res_i22 = (res_i15 * res_i15) and res_i22 = res_i26 and res_i30 = (res_i15 + 1)) and !(res_i26 > 9 and res_i15 >= 0))))
to be UNSAT. Consequently, the loop will not terminate.
