This is the contract, and it's OK. I don't think however that this is 
what was intended by OP. Rather, that calling a non-const function may 
repack/reallocate a QCC (*), causing invalidation of all references and 
iterators, even if the container was NOT shared in the first place.

Did I misunderstand the problem?

(*) Qt Contiguous Container
