Comment (by stefan):

 Note to self: This is due to np.int32 being derived from the Python int
 type.  On 64-bit systems, the results are the opposite way around:

 {{{
 In [4]: 0.0**np.int32(-3.5)
 Out[4]: inf

 In [5]: 0.0**np.int64(-3.5)
 <type 'exceptions.ZeroDivisionError'>: 0.0 cannot be raised to a negative
 power
 }}}
