`AssertionError: isdefined(cache[mi], :inferred)` on julia nightly for some functions

[KristofferC]

Tried to "ascend" from SnoopCompile into

   _precompilepkgs(::Vector{Base.PkgId}, ::Bool, ::Bool, ::Bool, ::Bool, ::Bool, ::Vector{Pair{Cmd, Base.CacheFlags}}, ::IOContext{IO}, ::Bool, ::Bool, ::Bool)

and got:

Maybe better MWE:
