UndefRefError: access to undefined reference

[wsmoses]

using Enzyme
Enzyme.API.printall!(true)

function bad(@nospecialize(t))
    t = Tuple{t...}
	return Base.unwrap_unionall(t)
end

@show bad((Int64,))
flush(stdout)

@show Enzyme.fwddiff(bad, Duplicated, Duplicated((Int64,), (Int64,))) #,(Int64,)))
