In the loop head node, references [i46] were interesting.
By SMT, we could prove
(0 <= initial_i10 and ((((path1_i46 = path1_i51 and path1_i54 = (path1_i51 + -1) and path1_i54 = res_i46 and path1_i10 = res_i10 and path1_i46 = initial_i46 and path1_i10 = initial_i10) and path1_i51 <= 0) or ((path2_i46 = path2_i52 and path2_i55 = (path2_i52 + 1) and path2_i55 = res_i46 and path2_i10 = res_i10 and path2_i46 = initial_i46 and path2_i10 = initial_i10) and path2_i52 > 0)) and (((res_i46 = res_i51 and res_i54 = (res_i51 + -1)) and !res_i51 <= 0) and ((res_i46 = res_i52 and res_i55 = (res_i52 + 1)) and !res_i52 > 0))))
to be UNSAT. Consequently, the loop will not terminate.
