In the loop head node, references [i90] were interesting.
By SMT, we could prove
(2 <= initial_i7 and (((path1_i90 = path1_i102 and path1_i105 = (path1_i91 + path1_i102) and path1_i107 = (path1_i102 + -1) and path1_i107 = res_i90 and path1_i105 = res_i91 and path1_i92 = res_i92 and path1_i7 = res_i7 and path1_i90 = initial_i90 and path1_i91 = initial_i91 and path1_i92 = initial_i92 and path1_i7 = initial_i7) and path1_i102 < 0) and ((res_i90 = res_i102 and res_i105 = (res_i91 + res_i102) and res_i107 = (res_i102 + -1)) and !res_i102 != 0)))
to be UNSAT. Consequently, the loop will not terminate.
