Assigning large object array to bool-specified slice of float array crashes Python

[acdr000]

Running Python 2.7.10, numpy 1.9.2, Windows 7, 64-bit AMD processor.
I'll let code do the talking:

Python 2.7.10 (default, May 23 2015, 09:44:00) [MSC v.1500 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import numpy as np
>>> f_arr = np.zeros((1000,))
>>> o_arr = np.ones((100,), dtype=object)
>>> b_arr = np.zeros((1000,), dtype=bool)
>>> b_arr[:100] = True
>>> f_arr[b_arr] = o_arr

This last line is supposed to set the first 100 elements of f_arr to 1. Instead, it crashes Python. This does not crash for significantly smaller arrays. I unfortunately cannot debug the underlying numpy code.

Found the bug, simple thing of the iterator not needing api, but the transfer function needing it.
