possible test failure in upcoming Julia version 1.5

[rfourquet]

A PkgEval run for a PR which changes the generated numbers for randn! indicates that the tests of this package might fail in Julia 1.5 (and on Julia current master). Apologies if this is a false positive.

Thanks a lot for opening this. Could you please link me to the new randn! ? (okay sorry I missed the PR link).

I certainly also have to add a seed! to the tests.

The tests fail also in another PkgEval run for a change in rand(a:b) (JuliaLang/julia#29240).

Also, you might be interested in using the new StableRNGs.jl registered package, which provides guaranteed stable streams of random numbers across Julia releases.

I can't reproduce these failings anymore in Julia 1.5.0-rc1. Seems the problem fixed itself :D
