Error revising: No method matching a functor created by JLLWrappers

[mbauman]

This is like the opposite of an MWE, but I've received a report of a Revise evaluation error while updating packages because a gensym'ed functor didn't have a method it was expecting.

I've not found this posted before here, but I found a very similar stacktrace on the Julia issue tracker: JuliaLang/julia#34598 (comment). There's quite a similarity here — both are trying to find a method for what look to be anonymous/gensym'ed functor created by a JLLWrappers macro.

This may be a naming inconsistency, i.e., an instance of gensymmed names changing because Revise has to re-parse the source code. AFAICT the true fix is to move pieces of Revise into Base, but that's still a bit in the future.
