Problem
TraceDescriptorsdeclares a pure virtual method (fillParams()) andis inherited by several derived classes (
TraceDscFromValues,TraceDscFromMsg,TraceDscFromDsc), but its destructor was notvirtual. Deleting a derived object through a
TraceDescriptors*pointer would result in undefined behavior, since the derived class's
destructor would not be called.
Fix
Added an explicit
virtual ~TraceDescriptors() = default;destructor.
