Description
I'm testing the build of matplotlib 2.0.0b1 by building 64 and 32-bit manylinux wheels and then testing on a matching (64 / 32 bit) docker container.
The test runs have picked up a couple of not-replicable errors for Python 3.5.0 and 32-bits. I wanted to flag these here in case y'all have an idea what might be going on, and to record in case anyone else hits the same problems.
One run stalled:
matplotlib.tests.test_axes.test_stackplot.test ...
No output has been received in the last 10m0s, this potentially indicates a stalled build or something wrong with the build itself.

Another generated a segfault:
matplotlib.tests.test_figure.test_figure.test ... Fatal Python error: Segmentation fault

I guess this may be an error in the blas library of numpy (OpenBLAS 0.2.18, 32-bit), but I haven't seen it since:

I guess it would be worth trying to track that one down (sigh).
