I don't know what assert you mean here, and I know of nothing in the code 
preventing you from creating two QModelIndexes with different internal 
pointers and referring to the same item. I also know that you can create 
QModelIndexes dynamically and you don't have to keep them around.

I suspect a bug in Qt or your model. You'll have to create a minimal 
testcase which hits the assert. That belongs in a bug report then, not in 
this thread.

Thanks,

Steve.
