>>> from numpy import *
>>> core.__version__
'0.9.5.2019'
>>> v = linspace(0, 2*pi)
>>> c = (255<<24)*cos(v) + (255<<16)*cos(v+2*pi/3) + (255<<8)*cos(v+4*pi/3) + 255
>>> c.astype(UInt32)
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
SystemError: Objects/longobject.c:257: bad argument to internal function
