World age assertion in codegen

[Keno]

After pulling master today, my current project is giving the following assertion error:

Assertion `li->min_world <= world && li->max_world >= world' failed.

Cursory debugging suggests the method has been deleted in the current world. Investigating further.

(rr) p li->min_world
$9 = 25116
(rr) p world
$11 = 28906
(rr) p li->max_world
$14 = 28839

[Keno]

Looks like this is happening while compiling

load_proto(TensorFlow.tensorflow.AttrValue) [ World Bounds 28897:∞ ]
_isfilled(TensorFlow.tensorflow.AttrValue_ListValue, Symbol, Bool) [ The li from above ]

which are part of TensorFlow.jl/ProtoBuf.jl. This is odd, because the _filled method was deleted before the load_proto was created so it shouldn't have been able to see it.

I just rebuilt julia and this went away. I do still have the rr trace if we want to do some debugging, but this is fairly mysterious. Maybe @vtjnash has an idea where to look.

Were you using Revise? If so, and if you hadn't updated packages in a while, it could have been timholy/Revise.jl#191.

[Keno]

Revise was loaded, but the method in question was not deleted by Revise. Rather it got invalidated when another package was loaded.

I still see this intermittently every time I rebuild julia. Just rebuilding again makes it go away, but it's definitely not fixed. I also did upgrade to mater of Revise in the meantime, just in case (but the error's still there).

This is pretty old now, so I'm going to presume it fixed by #31191 and see if any new issues get opened as they pop up.
