test_case.ii - compile with g++ -fsanitize=vptr; gives bogus "undefined
reference to `typeinfo for LogListener'"

The attached file shows with "g++ -fsanitize=vptr" (among others):

   undefined reference to `typeinfo for LogListener'

without "-fsanitize=vptr" only the expected undefined references appear.
