Value	Usage
0xCDCDCDCD	Allocated in heap, but not initialized
0xDDDDDDDD	Released heap memory.
0xFDFDFDFD	"NoMansLand" fences automatically placed at boundary of heap memory. Should never be overwritten. If you do overwrite one, you're probably walking off the end of an array.
0xCCCCCCCC	Allocated on stack, but not initialized

// Typical usage:
// class Foo { /* ... */ };
// class Bar : public Foo { /* ... */ };
 // Foo * pFoo = new Bar;
 // Bar * pBar = checked_cast<;Bar *>;(pFoo);
