Hi Florian,

Just want to give you a heads up that we observe crash downstream at this line. In particular, std::next(Target->getIterator()) returns null. So far I have internal reproducer only. Maybe you can figure out the problem faster than I come  up with upstreamable reproducer. Thanks in advance.
