state[1] += data
state[2] ^= state[1]    #这里有问题
state[2] -= rot(state[1],14)
state[0] ^= state[2]
state[0] -= rot(state[2],11)
state[1] ^= state[0]
state[1] -= rot(state[0],25)
state[2] ^= state[1]
state[2] -= rot(state[1],16)
state[0] ^= state[2]
state[0] -= rot(state[2],4)
state[1] ^= state[0]
state[1] -= rot(state[0],14)
state[2] ^= state[1]
state[2] -= rot(state[1],24)

return state

state[2] ^= state[1]

state[1] * state[2]的值太大，超过了int可以表示的范围

一、[0xdeadbeef + val] * 3，这个乘以3是不是已经溢出了，你把0xdeadbeef换成一个比较小的数试试
二、或者把dtype=np.uint32改成dtype=np.float64，或者更大的数据类型试试。
三、更新成python3.4，参考https://bugs.python.org/issue21816
