Q:

Julia 0.0.6 LoadError on ODE solve

I am trying to solve a simple Lotka Volterra model
using DifferentialEquations
f2 = @ode_def_nohes LVtest begin
  dx = x*(1.0 - A*x - B*y)
  dy = y*(rho - C*x - D*y)
end A B C D rho

u0 = [1;1]
tspan = (0.0,300.0)
p = [0.2,0.3,0.35,0.2,0.25]
prob = ODEProblem(f2,u0,tspan,p)
sol = solve(prob,Tsit5())

This returns the error:
ERROR: LoadError: InexactError()

A:

The problematic line is:
u0 = [1;1]

which produces Vector{Int}. Change it to:
u0 = [1.0,1.0]

or
u0 = Float64[1,1]

and all will work.
