This check flags all calls to c-style vararg functions.
Passing to varargs assumes the correct type will be read. This is
fragile because it cannot generally be enforced to be safe in the
language and so relies on programmer discipline to get it right.
This rule is part of the "Type safety" profile of the C++ Core
Guidelines, see
