My suggested solution:
In the header:
Put those functions in an inline namespace. (Or a normal namespace followed
by an using declaration).
In one translation unit, keep an exported version of the old symbols which
calls the new symbol in the namespace, to keep binary compatibility.
That way, the problem is solved if the application is compiled against Qt 5.1
or later.
If the application or one linked library is compiled against QtQml or
QtDeclarative from 5.0, and that this library uses one of the problematic
symbol, the crash can still happen. So one must still not link both QtQml,
QtDeclarative, and an old library together.
