Thanks for testing.  I get your test_la_roots failure too:

http://nipy.bic.berkeley.edu/builders/manylinux-2.7-ubuntu-32/builds/0/steps/shell_11/logs/stdio

http://nipy.bic.berkeley.edu/builders/manylinux-3.4-ubuntu-32/builds/0/steps/shell_11/logs/stdio

http://nipy.bic.berkeley.edu/builders/manylinux-3.5-ubuntu-32/builds/0/steps/shell_11/logs/stdio

I also get this on Pythons 3.4, 3.5:

======================================================================
FAIL: test_qhull.TestUtilities.test_more_barycentric_transforms

AssertionError: ndim=4 (array([11618], dtype=int32),)

I guess these are precision errors, and I guess we are also not
testing routinely on 32-bit Linux.

I think the next step is to see whether we get the same failures on
scipy master, with and without openblas 0.2.18, then make an issue for
them.

Cheers,

Matthew
