Precompilation failure when registering functions that with a vector type

[longemen3000]

MWE:
main module:

module TestSymFailure
    abstract type FailureModel end
    f(m::FailureModel,a1,a2,x = [1.0]) = sum(x)*f0(m,a1,a2)
    f0(m::FailureModel,a1,a2) = a1 + a2
    struct Failure <: FailureModel end
end # module

Symbolics Extension:

module SymExt
    using Symbolics
    using TestSymFailure
    @register_symbolic TestSymFailure.f(model::TestSymFailure.FailureModel,a1,a2,x::AbstractVector{<:Number})
    @register_symbolic TestSymFailure.f(model::TestSymFailure.FailureModel,a1,a2,x::Symbolics.Arr{Num,1}) false
end
