ndarray broken for linux aarch64 #97
Description
The unit ndarray-eigen unit test fails when compiling for linux aarch64 with gcc
(gcc9 from Ubuntu 20.04 or conda build environment)
This patch fixes the problem.
The intermediate m1+m2 assigned to an ndarray yields some slightly different
matrix element floats compared to m3.
