It's not good that you get a memory corruption in this case but it's
very not-good to try to get rid of objects by any sort of become
trickery. Find the objects pointing to them and use an inspector (or
even send messages! What a concept :-) to nil out those pointers. The
offending unwanted objects will then disappear.
If you provide some code to illustrate how the OM gets corrupted we can
try to debug it. I recently did soem work on stopping objectA become:
objectA crashes and it's conceivable this is related.
