No, this is not correct, good catch. It should be:
| slots |
self flag: #Dan.
(self isIntegerObject: oop) ifTrue:[^0].
slots := self slotSizeOf: oop.
(self isBytesNonInt: oop)
ifFalse:[^slots * ObjectMemory bytesPerWord]
I've clean a lot of this crud out of the interpreter, but there are bound
to be a few more that we have not spotted yet.
