Error when descending into function

MWE:

Symbolics @ https://github.com/JuliaSymbolics/Symbolics.jl/commit/967d872fee6695a796e7142e232158fefd0272aa
Cthulhu@2.17.10

julia> using Revise, Cthulhu
julia> using Symbolics
julia> descend(Symbolics.executediff, Tuple{Differential, Symbolics.SymbolicT})

In [T]yped code mode, with [w]arn, [t]ype annotations and [o]ptimize enabled. First, R to revise and redisplay (due to #688). Then, attempting to descend into

invoke #executediff#97(::Bool,::Bool,::typeof(Symbolics.executediff),::Differential,::SymbolicUtils.BasicSymbolicImpl.var"typeof(BasicSymbolicImpl)"{SymReal})::SymbolicUtils.BasicSymbolicImpl.var"typeof(BasicSymbolicImpl)"{SymReal}

(The only option) errors with

ERROR: AssertionError: length(infos) == length(info.results)

Reproduce the failure with the Symbolics and Cthulhu versions, using descend(Symbolics.executediff, Tuple{Differential, Symbolics.SymbolicT}) in the stated mode and revising first. Start at src/reflection.jl:189, where the length assertion fails, and trace the surrounding reflection code. Done means descending into the shown invoke method no longer raises this AssertionError.
