Gabriele Comoretto [X], are you in a position to see if this solves your problem? I'm pretty confident it fixes the particular failure you saw, but it's possible that will just reveal more failures.
I am setting up an environment and I will try to build it manually
I have executed a couple of runs, one manually, and one on a test Jenkins, using the fix, and I did not get the error.
The problem is just when building in Linux.
Numpy new version is 1.5.4. The old version is 1.4.5.
Scipy new version is 1.2.0. The old version is 1.1.0.
In attachment the sdiff between environemnts.
