QList iterators validity differs from C++ standard

When converting some code from std::list to QList I got some unexpected crashes. I found that the problem is that QList handles iterators validity in a non-conforming way (as per the C++ standard)

I am attaching a file where you can see the different behaviour. In short: QList::clear() invalidates a stored QList::end() iterator, while the C++ standard says that the end() iterator should remain valid.

I am reporting this as a bug because I understand that the whole point of having iterators in QList is for C++ compatibility.
