3.3.6 doesn't report about 'control reaches...'.
4.0 and 4.2 not tested.

There are two different bugs here.  The first testcase is a dup of PR 20681. 
The second testcase is a dup of bug 25973.

Second those are not unused objects as they have side effects on their
constructors/deconstructors.

I am going to close this as invalid based on the second reason as you seem to
blame that first.
