cunumeric.mean with dtype=np.complex64 causes fatal python error

[robinwnv]

arr_num = num.random.randint(-5, 5, size=(1,))
dt = np.complex64
num.mean(arr_num, dtype=np.dtype(dt))

In Numpy, pass
In cuNumeric, although the case pass, the whole test aborted with fatal python error.
For dt=np.float32 or np.int32, pass for cuNumeric.
