Or it could be a bug where the VM ends up getting a SmallInteger instead of a
CompiledMethod as the result of a method lookup. That would be bad...

you can ask the method directly
Object allSubclasses flatCollect: [ :each | each methods select: [
:method | method hasLinks ] ]
this is much faster as it returns immediately nil for methods without links
(without AST reification).
