  • Diagnostic 809: exception specification for virtual entity-kind "entity" is incompatible with that of overridden entity-kind "entity"

    Cause:

    Overidden virtual functions should have exception-specification at least as restrictive as its own. A caller function might not be able to catch if derived threw an exception that was not advertised in the base class function.
