Do any languages actually do this? Do any languages somehow use their GC to update references when a growable array is reallocated? I'm not aware of any language that does. Furthermore, its hard to see how it could. In the case of a simple copying/compacting collector the whole world is stopped and the pointer graph traced. But you obviously can't do that every time a growable array needs to be reallocated. I understand that there are more complex solutions that avoid that pause, but still not any I'm aware of that would be exploitable for reallocating an array.
