Hello Joe,
The problem with your example is a simple one.
We can not reproduce it to investigate.
The code you attached has no TIter and TFile dtor has no TIter
either. To understand your troubles quickly and avoid the guess job
you should submit further information (you debugger had provided for sure)
The first question will be what application we are talking about ?
Is it root.exe with your custom DLL loaded in ? I guess no.
Best regards, Valeri
