Just type

PositionableStream>>#fileInAnnouncing:

and explore it. Look for the literal pointing to the compiler (literal8 here). Toggle that open and toggle open the value. Look at the instanceVariables - does it still have sourceStream?

As to the explorer, did you open one? Is it still open? (The PointerFinder says it is) Could it have been open when the image was last saved?

Also, you could do

Behavior allSubInstances select: [ :e | (e asString findString: 'Compiler') > 0]

Do you get: an OrderedCollection(ClosureCompilerTest CompilerTest CompilerExceptionsTest CompilerNotifyingTest CompilerSyntaxErrorNotifyingTest Compiler ClosureCompilerTest class CompilerTest class CompilerExceptionsTest class CompilerNotifyingTest class CompilerSyntaxErrorNotifyingTest class Compiler class)

I don't know how I would do that. The bytecode just says pushLit: Compiler.

But if I say Compiler allInstances collect: [:c | c instVarNamed:
'cue'] I see {nil . a CompilationCue . a CompilationCue}. That first
one's a problem! Further, my image has an ObjectExplorer (!) hanging
onto that Compiler, coming from I don't know where.

If you inspect

and look at the literal for Compiler, does it look to be pointing to the new
or old Compiler?

I'm running with Compiler-nice.274.

What's weirder is in that top stack frame (Compiler >>
#evaluate:in:to:notifying:ifFailed:logged: the following all show up
as red, because they're references to instvars that don't exist:
class, sourceStream, context, requestor.

That's because the CompiledMethod that's running is not actually the
right CompiledMethod! It's from some ancient pre-CompilationCue
Compiler instance. Or at least so I suspect because that Compiler
instance has a nil 'cue' instvar.

If it helps, the PointerFinder says this of the offending context:

globals: Environment
declarations: IdentityDictionary
#World -> PasteUpMorph
submorphs: Array
1: SystemWindow
model: ObjectExplorer
currentSelection: ObjectExplorerWrapper
item: CompiledMethod

In contrast, PointerFinder on: (Compiler >>
#evaluate:in:to:notifying:ifFail:logged:) says:

CLASS: SmalltalkImage class
superclass: Object class
subclasses: Array
445: Compiler class
methodDict: MethodDictionary
array: Array
39: CompiledMethod.
