From a9416dc62c36079b93b4951c894a0b15e53bb38c Mon Sep 17 00:00:00 2001 From: Markus Armbruster Date: Fri, 3 Mar 2017 13:32:46 +0100 Subject: tests: Cover input visit beyond end of list When you try to visit beyond the end of a list, the qobject input visitor crashes, and the string visitor screws returns garbage. The generated list visits never go beyond the list end, but manual visits could.
