You can't access that variable without changing the Qt sources. What you can do though is to override malloc/free/new/delete with your own functions which zero-out any memory thats free'd/delete'd and tell Qt to use your versions of the memory-allocation/de-allocation. Maybe there's also an existing allocator you could just plugin into your app that achieves what you want.
