1.1.0-6 puts us in the clear with respect to the MemoryError failures.

10/10 test runs passed in unstable

9/10 test runs passed in testing.


The one failure is odd.  It's not in the same class as previous test 
failures, not a MemoryError.

It appears to be a true test failure, failing 
_trustregion_constr.tests.test_canonical_constraint.test_concatenation
in 
/usr/lib/python2.7/dist-packages/scipy/optimize/_trustregion_constr/tests/test_canonical_constraint.py:179 
with

        if np.any(f0[mask] < lb[mask]) or np.any(f0[mask] > ub[mask]):

                             "set to True.")
E           ValueError: `x0` is infeasible with respect to some 
inequality constraint with `keep_feasible` set to True.



This happens in the atlas tests (atlas provides lapack/blas), which is 
not core scipy as such, since lapack can be provided by openblas.

This particular failure only happened once.
