Segfault with OrdinaryDiffEq and Enzyme

[efaulhaber]

I'm getting a segfault with this MWE:
Update: reduced the MWE even more:

using OrdinaryDiffEq, ADTypes, Enzyme

function f(du, u, p, t)
    du .= u
    return nothing
end

u0 = [1.0 0.5; 0.5 1.0]
tspan = (0.0, 1.0)
prob = ODEProblem(f, u0, tspan, nothing)

# Getting a segfault here
sol = solve(prob,
            Rodas5(autodiff=AutoEnzyme(mode=set_runtime_activity(Enzyme.Forward),
                                       function_annotation=Enzyme.Duplicated)),
            save_everystep=false)

Sometimes I get this:

julia> include("mwe.jl")
ERROR: LoadError: First call to automatic differentiation for the Jacobian
failed. This means that the user `f` function is not compatible
with automatic differentiation. Methods to fix this include:

1. Turn off automatic differentiation (e.g. Rosenbrock23() becomes
   Rosenbrock23(autodiff = AutoFiniteDiff())). More details can befound at
   https://docs.sciml.ai/DiffEqDocs/stable/features/performance_overloads/
2. Improving the compatibility of `f` with ForwardDiff.jl automatic
   differentiation (using tools like PreallocationTools.jl). More details
   can be found at https://docs.sciml.ai/DiffEqDocs/stable/basics/faq/#Autodifferentiation-and-Dual-Numbers
3. Defining analytical Jacobians. More details can be
   found at https://docs.sciml.ai/DiffEqDocs/stable/types/ode_types/#SciMLBase.ODEFunction

Note: turning off automatic differentiation tends to have a very minimal
performance impact (for this use case, because it's forward mode for a
square Jacobian. This is different from optimization gradient scenarios).
However, one should be careful as some methods are more sensitive to
accurate gradients than others. Specifically, Rodas methods like `Rodas4`
and `Rodas5P` require accurate Jacobians in order to have good convergence,
while many other methods like BDF (`QNDF`, `FBDF`), SDIRK (`KenCarp4`),
and Rosenbrock-W (`Rosenbrock23`) do not. Thus if using an algorithm which
is sensitive to autodiff and solving at a low tolerance, please change the
algorithm as well.
