random.randint failure with large int64s on windows #6812
Description
clearly using platform ints internally. But I think this should upcast in the case of overflow?
In [21]: np.random.randint(np.iinfo(np.int32).min,np.iinfo(np.int32).max,10)
Out[21]:
array([ -397752718, -1983241147, -920985850, -2131569981, -769723972,
