[Numpy-discussion] Failed numpy.test() with numpy-1.10.1 on RHEL 6

[Lintula]

Hello,

I'm setting up numpy 1.10.1 on RHEL6 (python 2.6.6, atlas-3.8.4,
lapack-3.2.1, gcc-4.4.7), and this test fails for me. I notice that
someone else has had the same at
https://github.com/numpy/numpy/issues/6063 in July.

Is this harmless or is it of concern?
