[Numpy-discussion] Warnings not raised by np.log in 32 bit build on Windows

I'm investigating a test error in scipy 0.13.0 beta 1 that was
reported by Christoph Gohlke. The scipy issue is here:
https://github.com/scipy/scipy/issues/2771
I don't have a Windows environment to test it myself, but Christoph
reported that this code:
```
import numpy as np
data = np.array([-0.375, -0.25, 0.0])
s = np.log(data)
```
does not generate two RuntimeWarnings when it is run with numpy 1.7.1
in a 32 bit Windows 8 environment (numpy 1.7.1 compiled with Visual
Studio compilers and Intel's MKL). In 64 bit Windows, and in 64 bit
linux, it generates two RuntimeWarnings.
The inconsistency seems like a bug, possibly this one:
https://github.com/numpy/numpy/issues/1958.
Can anyone check if this also occurs in the development branch?
