Solving an ODE with default options is fine, specifying an option results in a type instability. Perhaps related to #2530.

using OrdinaryDiffEq

prob = ODEProblem{false}((u, p, t) -> -u, 1.0, (0.0, 1.0))

@code_warntype solve(prob) # type stable
@code_warntype solve(prob, reltol = 1E-3) # type unstable

I see similar behavior when specifying abstol and dt.

I'm using Julia 1.11.2 and OrdinaryDiffEq.jl v6.90.1
