    XFAIL a test in g++.dg/warn/Wstringop-overflow-4.C
    
    As per the explanation in the test, and in the DOM conversion to
    ranger patch, this is a known regression.  I had mentioned I would
    XFAIL this test, but forgot to do so.  There is an analysis in the
    test itself as to what is going on.
    
    Tested on x86-64 Linux.
    
    gcc/testsuite/ChangeLog:
    
            * g++.dg/warn/Wstringop-overflow-4.C: XFAIL a test.
