Bug 214209: math/py-numpy segmentation faults.
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D214209



--- Description ---
The current py27-numpy 1.11.1,1 source and package is not usable due to
segfaults.  This appears to be related to the BLAS libraries.  I have tried
compiling against all 3 libraries, but the segfault is always present.	To
reproduce:

$ python
Python 2.7.12 (default, Oct 29 2016, 14:13:15)=20
[GCC 4.2.1 Compatible FreeBSD Clang 3.8.0 (tags/RELEASE_380/final 262564)] =
on
freebsd11
Type "help", "copyright", "credits" or "license" for more information.
>>> import numpy
>>> numpy.test('full')
Running unit tests for numpy
NumPy version 1.11.1
NumPy relaxed strides checking option: False
NumPy is installed in /usr/local/lib/python2.7/site-packages/numpy
Python version 2.7.12 (default, Oct 29 2016, 14:13:15) [GCC 4.2.1 Compatible

Setting the verbose flag gives some more info:

>>> numpy.test('full', verbose=3D10)
