+    runtime with instrumentation for vtable verification. All virtual
+    functions in the standard library will be verified at runtime.
+    Types impacted include <classname>locale</classname> and
+    <classname>iostream</classname>, and others.  Disabling means that
+    the C++ runtime is compiled without support for vtable
+    verification. By default, this option is off.
