Comment(by mwiebe):

 The function which should be doing the initialization which seems to be
 failing is here in the "else" case:

 https://github.com/numpy/numpy/commit/aed9925a9d5fe9a407d0ca2c65cb577116c4d0f1#L11R2580

 I've tried it on a Mac with 64-bit Python 2.7.1, built with llvm-gcc
 4.2.1, but it didn't reproduce there either.

 Can you try a few other reductions that trigger the same code-path?
 Instead of "a.max(0)", try "np.maximum.reduce(a, axis=0)"? The functions
 np.minimum.reduce, np.fmin.reduce, np.fmax.reduce should trigger it too.
