2077db1be5 Commit the vtable verification feature.
Commit the vtable verification feature.  This feature is designed to
detect, at run time, if/when the vtable pointer in a C++ object has
been corrupted, before allowing virtual calls through that pointer. 
If pointer corruption is detected, execution of the program is halted.
