In the loop head node, references [i289, i290] were interesting.
By SMT, we could prove
((initial_i289 <= 0 and initial_i290 <= 0 and initial_i73 <= 0 and initial_i157 <= 0 and 4 <= initial_i30) and (((path1_i321 = (path1_i289 * path1_i290) and path1_i321 = path1_i326 and path1_i340 = (path1_i289 + -1) and path1_i342 = (path1_i290 + -1) and path1_i340 = res_i289 and path1_i342 = res_i290 and path1_i73 = res_i73 and path1_i157 = res_i157 and path1_i30 = res_i30 and path1_i289 = initial_i289 and path1_i290 = initial_i290 and path1_i73 = initial_i73 and path1_i157 = initial_i157 and path1_i30 = initial_i30) and path1_i326 > 0) and ((res_i321 = (res_i289 * res_i290) and res_i321 = res_i326 and res_i340 = (res_i289 + -1) and res_i342 = (res_i290 + -1)) and !res_i326 > 0)))
to be UNSAT. Consequently, the loop will not terminate.
