There is an integer overflow on min() statements because python incorrectly checks the length to put the overflow message, so it is possible to overflow min()
min(0xFFFFFFFFFFFFFFF+100000**8000000000)
That line freezes python until you restart it, which is basically as if you were crashing it, the effect is the same, python stops working.
Hope it helps ;)
