This sounds good, while agreeing with the comments so far. It's tempting to say that "anyone who's allocating a massively sized stack variable is asking for trouble" and to not support that situation well. Unfortunately that's also exactly the scenario where developers probably want their debugger to work well. What are the implications of over-sized types being ignored by this code, are there any correctness issues or is it just efficiency?
