That shouldn't be a problem; stackPointerIndex is pretty much limited to 32 words, arraySize is practically limited to quite small but could possibly get large in insane code and cntxSize is 40 (-ish?) words
primitiveObjectAtPut primitiveObjectAt
self success: index <= ((self literalCountOf: thisReceiver) +LiteralStart).
again, operating inside methods/context/etc so fairly limited value range. literal count is limited to 256 I think, LiteralStart is 6 or thereabouts.
postGCAction (self sizeOfFree: freeBlock) > shrinkThreshold
Looks like sizeOfFree returns a signed int. shrinkThreshold should only be a +ve number anyway and should be checked somewhere in the setting of its value. Guess sizeOfFree ought to be changed.
