It would require compiler support.

It would require emitting pointer maps for each stack frame and each object.

It's relatively straightforward. If you align pointers on word 
boundaries, you only have to store one bit per word; else, one bit per 
byte; so this is not a terribly large overhead (no more than a couple 
bytes for a typical function, probably).

It wouldn't be terribly fast, but it probably wouldn't be an extreme 
slowdown either, most likely.
