This one is on me, I think, in #10602. I wasn't aware this was legal:
>>> np.__version__
'1.13.3'
>>> class Custom(np.void): pass
>>> np.dtype(Custom)
dtype('V')
>>> np.__version__
'1.16.0.dev0+7af8e10'
>>> class Custom(np.void): pass
>>> np.dtype(Custom)
RuntimeError: Internal error: NumPy dtype unrecognized type number
Not sure if this affects 1.15.0
