It is. Semantics being: if any item with key=8 is in the map, return a reference to it. If not, add a new item with key=8 and value=int()=0

After these changes, there is no item with key=8 in the map, hence the expression is going to cause the creation of such an item, with value=0. Thus, there should be no way to match 1234567 in the expression output :)

For the test to succeed with ToT clang, one would have to remove the error=True clause from the expect() call, but that would cause the test to fail for everyone who *does not* have ToT clang (and I expect this latter to be a much wider audience than the former).
We should be checking for which version of clang built the binary and have two versions of this expect call in place, one with error=True for older-than-bug-fixing-clang and one without for bug-fixing-or-greater revisions, but I guess that only makes sense once people start adopting the new clang and complaining :-)
