Yep. I have it enabled, just looking for more ways to trap this type of error sooner. >> What I was wondering is does anyone know how we could extend this >> further?

I am assuming that a XxxPtr type could check the field container it is pointing to and see if it has it's internals cleared to say that it is actually not valid anymore. So basically putting up a big red flag whenever someone tries to access a dead object. Maybe this doesn't work well with the current architecture. I really don't know because I can't see to understand the low-level details of the current system. :( > >> If we had that, then I think it would >> stop the application in it's tracks the first time it tries to use an >> fc that is not valid anymore. >> >> Would this work?
