New Synopsis: No warning for referencing a temporary

State-Changed-Why:
    Not a bug.  The cast converts your lvalue to an rvalue, which
    leads you referencing a temporary rather than the variable 
    that you intended.
    
    It would be Really Nice if -Wall would diagnose this, so I'm
    leaving the PR open, and re-categorizing it.
