Tests failing on nightly

[ivarne]

After JuliaLang/julia#5810 (comment), we get deprecation warnings, and failing tests due to a missing broacasting operator .\(Array{Float64,2}, Int64) in ODE.jl#L354. I do not feel confident enough to say what is really happening here.

The problem is that in the first tests jac (Jacobian) is a matrix with one element while F is just a scalar. In the old days this used to work ... In JuliaLang/julia#14 I handle the scalar case separately and this error doesn't occur. There are, however, also depreciation warnings, which are kind of strange. Could someone please try this

julia> midxdot = Array(typeof([1., 2.]), 4);

julia> fill!(midxdot, [1.,2.]);

julia> [1. 2. 2. 1.]*midxdot
WARNING: x::Number + A::Array is deprecated, use x .+ A instead.

 in generic_matvecmul at linalg/matmul.jl:274
 in * at linalg/matmul.jl:267
1-element Array{Any,1}:
 [6.0,12.0]

which seems to be wrong? (Edit: The result is correct of course, but the warning is strange?)

I could probably fix the issue with \, but I think we should move on and merge JuliaLang/julia#14 and then address JuliaLang/LinearAlgebra.jl#94 separately.

Should be solved by JuliaLang/julia#16 which avoids generic_matvecmul and thus JuliaLang/LinearAlgebra.jl#94.
