SDEProblem segfault during solve when built from SDEFunction

[sebapersson]

Describe the bug 🐞

When I create a SDEProblem from a SDEFunction I built via a SDESystem I get sefault when trying to solve an EnsembleProblem for large enough trajectories. Bug does not happen if I build the SDEProblem directly from a SDESystem or ReactionSystem.

Expected behavior

I should not get a segfault.

Minimal Reproducible Example 👇

using Catalyst, StochasticDiffEq, ModelingToolkit, SciMLBase
using ModelingToolkit: t_nounits as t, D_nounits as D

@parameters c1 c2
@variables X(t) Y(t)
eqs = [D(X) ~ -c1*X + c2*Y,
       D(Y) ~ c1*X - c2*Y]
noiseeqs = [-sqrt(abs(c1*X)) sqrt(abs(c2*Y));
             sqrt(abs(c1*X)) -sqrt(abs(c2*Y))]
@named sdesys = SDESystem(eqs, noiseeqs, t, [X, Y], [c1, c2]; tspan = (0, 1000.0))
sdesys = complete(sdesys)

# SDESystem via Catalyst
rn = @reaction_network begin
    @species X(t)=50.0 Y(t)=100.0
    c1, X --> Y
    c2, Y --> X
end

u0 = [X => 50.0, Y => 100.0]
ps = [c1 => 0.5, c2 => 1.0]
sdefun = SDEFunction(sdesys, first.(u0), first.(ps))
sdefun = SDEFunction(sdesys, first.(u0), first.(ps))

sprob_fun = SDEProblem(sdefun, last.(u0), [0.0, 10.0], last.(ps))
sprob_sys = SDEProblem(rn, u0, [0.0, 10.0], ps)
sprob_rn = SDEProblem(sdesys, u0, [0.0, 10.0], ps)

#=
This section works as expected
eprob = EnsembleProblem(sprob_sys)
sol = solve(eprob, EM(), EnsembleSerial(), trajectories = 1000, saveat = 1:10, dt = 1e-3)
eprob = EnsembleProblem(sprob_rn)
sol = solve(eprob, EM(), EnsembleSerial(), trajectories = 1000, saveat = 1:10, dt = 1e-3)
=#

eprob = EnsembleProblem(sprob_fun)
sol = solve(eprob, EM(), EnsembleSerial(), trajectories = 10000, saveat = 1:10, dt = 1e-3)
