In the loop head node, references [i39] were interesting.
By SMT, we could prove
(0 <= initial_i7 and ((((path1_i39 = path1_i44 and path1_i47 = (path1_i44 + -1) and path1_i47 = res_i39 and path1_i7 = res_i7 and path1_i39 = initial_i39 and path1_i7 = initial_i7) and path1_i44 <= 0) or ((path2_i39 = path2_i45 and path2_i48 = (path2_i45 + 1) and path2_i48 = res_i39 and path2_i7 = res_i7 and path2_i39 = initial_i39 and path2_i7 = initial_i7) and path2_i45 > 0)) and (((res_i39 = res_i44 and res_i47 = (res_i44 + -1)) and !res_i44 <= 0) and ((res_i39 = res_i45 and res_i48 = (res_i45 + 1)) and !res_i45 > 0))))
to be UNSAT. Consequently, the loop will not terminate.
