So this is um....interesting....

(gdb) p small_ints[0]
$2 = (PyIntObject *) 0x558ce65df528
(gdb) p *small_ints[0]
$3 = {ob_refcnt = 18, ob_type = 0x7fe019b694c0 <PyInt_Type>, ob_ival = -5}
(gdb) p *small_ints[1]
$4 = {ob_refcnt = 65, ob_type = 0x7fe019b694c0 <PyInt_Type>, ob_ival = -3}
(gdb) p *small_ints[2]
$5 = {ob_refcnt = 204, ob_type = 0x7fe019b694c0 <PyInt_Type>, ob_ival = -3}
(gdb) p *small_ints[3]
$6 = {ob_refcnt = 1872, ob_type = 0x7fe019b694c0 <PyInt_Type>, ob_ival = -2}

When is 1/1=10? When -5 + 1 = -3.

So now I suppose the question is how this comes to be.
