Description
I'm getting an error I haven't seen reported, when trying to use Revise to track changes in Julia itself:

WARNING: redefinition of constant attr_list. This may fail, cause incorrect answers, or produce other errors.Then it hangs. Sometimes it gets to Error showing value of type ERROR: and then nothing.
For definiteness this is with JuliaLang/julia#43334, newly rebased. The PR does not change anything very deep. I don't know what attr_list is; I think I remember seeing this complaint before, but it still worked.
Edit: In fact I get the same error on master, thus no changes for Revise to handle at all:
