Failed scipy 0.15.1 tests on Linux (only with Python 3.4.2 x86_64) #243
Description
The scipy package was just updated to version 0.15.1 using Anaconda on a Linux server (CentOS 6.5) and a Linux workstation (Fedora 21). Seven tests failed (Python 3.4.2 x86_64). The same 7 tests failed for scipy version 0.14.0 and 0.15.0 with Python 3.4.2. The installation used is on both system is Miniconda.
For the same installation but using Python 2.7.9 instead, there were no failed test. No failed test for Python 3.4.2 on Windows either.
There are no failures when package is compile from source (i.e. installed using pip) on the same Fedora 21 workstation on Python 3.4.2 (compiled from source).
Here are the failures:
