Not a fool proof test since random values have a chance of being zero,
but it basically shows:
1. global old heap object NOT zeroed
2. local old heap object NOT zeroed
3. local class zeroed
4. global class zeroed
5. global old stack object zeroed
6. local old stack object NOT zeroed
7. global stack record zeroed
8. local stack record NOT zeroed.
I didn't bother with heap records but we can see what will happen
