Access to undefined reference Julia 1.9

[fredrikekre]

I get a UndefRefError: access to undefined reference on this line:

JuliaInterpreter.jl/src/utils.jl

Line 740 in b2ebd69

sparams = Core.svec(frame.framedata.sparams...)

where I have

frame.framedata.sparams = Any[#undef, Int64, typeof(identity)]

I don't have a (small) reproducer.

An MWE is:

julia> f(x::Union{Vector{T}, Nothing}) where {T} = x + 1
f (generic function with 1 method)

julia> @run f(nothing)
ERROR: UndefRefError: access to undefined reference

Where the sparam is undefined.
