undefvar and bounds error in linearization_function

[baggepinnen]

ModelingToolkit.jl/src/systems/abstractsystem.jl

Line 2170 in a7f6cd2

get_initprob_u_p = let p_getter,

@AayushSabharwal isn't there something missing in the expression let p_getter,?, e.g., let p_getter = p_getter,?

Making that change, I further get

ERROR: BoundsError: attempt to access Tuple{SymbolicIndexingInterface.ProblemState{Vector{Float64}, ModelingToolkit.MTKParameters{Tuple{Vector{Float64}}, Tuple{}, Tuple{}, Tuple{}, Tuple{}, RuntimeGeneratedFunctions.RuntimeGeneratedFunction{(:ˍ₋out, :ˍ₋arg1), ModelingToolkit.var"#_RGF_ModTag", ModelingToolkit.var"#_RGF_ModTag", (0x436e531f, 0xa1112b08, 0x3bf49a23, 0x855dd196, 0x09507fa9), Nothing}, RuntimeGeneratedFunctions.RuntimeGeneratedFunction{(:ˍ₋arg1,), ModelingToolkit.var"#_RGF_ModTag", ModelingToolkit.var"#_RGF_ModTag", (0xee8ca58d, 0x1958d6ce, 0x314ac4d0, 0xd540ea53, 0x6f246bd0), Nothing}}, Float64}} at index [2]

reproducer exists, but it's not very minimal
